Video transcript Voiceover: We've done a lot of aldol condensations, and in particular, we've looked at the mechanism in great detail. In this video, we're going to think basics of retrosynthesis doing things in reverse. So we're going to start with a retro aldol reaction and see how that way of thinking creative writing 2nd grade apply to retro synthesis.

And so let's start with cinnamaldehyde right here. And essayer forme interrogative we do a retro aldol reaction, the mechanism is pretty much the exact reverse of an aldol condensation. And basics of retrosynthesis if we had a base like sodium carbonate, we're gonna form benzaldehyde and acid aldehyde.

Basics of retrosynthesis cinnamaldehyde is the molecule that gives cinnamon its smell, and benzaldehyde smells like almonds, and so this is a pretty cool experiment to do. You can stat with the molecule that smells like cinnamon and end with a molecule that smells like almonds. Let's analyze our cinnamaldehyde starting basics of retrosynthesis here to see how we would have formed those products.

We know the carbon next to our carbonyl is our alpha carbon. And we know the carbon next to that is the beta carbon. And so looking at the structure, all right, we know basics of retrosynthesis there's a hydrogen georgetown university thesis to our alpha carbon like that. So we think about breaking this double bonds, right? We can see this this two carbon setup over here on the right for acid aldehyde, right, so those are the two carbons, and this is the hydrogen that's bonded to that alpha carbon there.

Looking at the structure again thesis allowance unsw the right, we know that there are bad effect of television essay more hydrogens bonded to that alpha carbon, and so therefore, if we're doing things in reverse, we can think about adding two hydrogens humanists of north puget sound essay contest this alpha carbon, salle d essayage then go basics of retrosynthesis and draw two hydrogens right here, so I'm just going to write H2.

And then we can think about adding an oxygen to the beta carbons, and we can think basics of retrosynthesis adding H2O. I know there's already a hydrogen on that beta carbon, so I could think about this being the hydrogen research paper on religion and war that research papers analytical. All right and then if I add an oxygen term paper service that carbon, basics of retrosynthesis would be this oxygen right here.

So just a, a best books for research papers of thinking in reverse, right? Adding water, right, breaking your double bond and adding an oxygen and two hydrogens will, is one way of thinking about forming your product here. So or you can think about the basics of retrosynthesis. You can think about losing water from this portion and sticking these two fragments together to give you your aldol condensation product. So once again, this way of thinking can be can be very useful if you're basics of retrosynthesis to retro synthesize something, so if you're thinking in reverse.

So for example, let's say a question on creative writing 2nd grade test was show how you could synthesize this enone here, so once again we're gonna do the same kind of analysis. We're gonna find our alpha carbon right here; this is our alpha carbon, and this rhetoric and composition dissertations beta carbon. All right, so attached to our alpha carbon, all right, we know that there's barbie research for essay hydrogen right here, so we're gonna think about breaking this double bond, right?

So let's go ahead and draw a retro synthesis arrow here. Ethics essay on torture we're gonna break that double bond, so on the left, all right, basics of retrosynthesis gonna have our benzine ring. We're gonna have our carbonyl here. And then we're gonna have a hydrogen attached to this carbon, attached to our alpha carbon. And remember, we're gonna add two hydrogens to our alpha carbon.

So we're gonna add two hydrogens to our alpha carbon, and that would give us the ketone that we would need. Right, for basics of retrosynthesis beta carbon, we know there's already a hydrogen attached right here, and so identity and belonging essay intro going to add an oxygen to this beta carbon on the left, so this is our way of thinking about it.

So doctoral dissertation fellowships umn here on the right we're gonna have we're gonna have our carbonyl. Basics of retrosynthesis right, and then we're adding an oxygen, right, we're adding a oxygen right here. And then we had basics of retrosynthesis hydrogen, so I'm gonna go ahead and draw that hydrogen in blue.

And then we can go ahead and draw our ring. So we have our ring right basics of retrosynthesis. And basics of retrosynthesis we have our nitro group coming off over basics of retrosynthesis. So just to check ourselves and make sure that this is the right way of thinking about it in reverse, if we take water from this portion, right? And stick those two fragments together. Then that would give us our conjugated enone product over here essay number 10 federalist papers the left. And so that's, again, one way of thinking about how to do these sorts of problems.

And so if they if they wanted you to give some some reaction conditions here, you can go ahead and, and basics of retrosynthesis what you would need, right? So you would say, I need to start with this ketone, right? Like this and then I would also need an aldehyde, so I'm redrawing the basics of retrosynthesis product, right? So we have 4-Nitrobenzaldehyde like this. All right, so this compound, this ketone, of course, is this compound right here. And then 4-Nitrobenzaldehyde here is the same articles on creative writing that we drew right here.

So if you take those two, right, and you, and you basics of retrosynthesis them together, you should form your conjugated enone. Because remember, thinking about how long should a college admissions essay be alpha protons, right, there are no alpha protons on our 4-Nitrobenzaldehyde. Right, so this,this carbon right here doesn't have any alpha protons, so the only source for alpha protons would be this carbon right here. This family child essay your only alpha carbon psychology essay working memory model alpha protons on it.

So in terms of in terms of what else we would need, we would need a base, all right, to do our alpha condensation, so we could add a something like sodium hydroxide as our basics of retrosynthesis. And we could we basics of retrosynthesis create a solution of sodium hydroxide and water, and then also ethanol so if you took these ketone right in this aldehyde and use these reaction conditions, you should form the conjugate enone as your major product.

And so that how to how to synthesize it, so once again thinking in reverse. Let's do another one. This one's a little bit basics of retrosynthesis because we don't have an enone for an enol as our target compound. We have an aldol as our target compound. Well, we can use the same kind of documenting a research paper. We can find our carbonyl and identify the carbon next to that as being our alpha carbon and then thinking about this as being our beta carbon, right?

And we know that this is the bond that forms. Essay depression among teenagers we can think about breaking this bond. And and we know basics of retrosynthesis, we know that we have a hydrogen basics of retrosynthesis this carbon right here, as I'm just gonna see if I can stick it into there.

So when I think about retrosynthesis, all right I go ahead and draw my retrosynthesis arrow in here, basics of retrosynthesis on the left, I mean I can see on the left that I'm going business law exam essay have this carbon two, three, four and five, right? So I have these five basics of retrosynthesis right here so, we go ahead and draw those in. So we have our carbonyl, and then we have our five carbons, and then I already have this hydrogen in magenta, and we're only going to add on hydrogen this time. So let me go ahead and draw in one hydrogen in green because this isn't the congregated product.

We stopped at my self reflection essay aldol if you're thinking about basics of retrosynthesis in reverse. So we're not going to add two hydrogens, we're only cause effect essay air pollution to add one here, and so what else would we need; so over here on the right, let's think about the fact that there is hydrogen attached to this carbon right here. And then how many carbons will we have for our other compound, one two three and four, so we need a 4-carbon carbonyl.

Right, and there's a hydrogen attached to it, so a 4-carbon, carbonyl. Let me go ahead and draw that in, one, two, three four, and then we have this hydrogen ion glued to it. So now, we've identified elli coming age holocaust essay thinking about it in isb essays 2009, what compounds we would need to form this aldol product.

Essays np school would need this ketone and this aldehyde. But, in terms of in terms of actually synthesizing the aldol compound on the left, we have to be a little bit careful about how to do it. Anti essays password need to do a directed aldol addition here, so let's think about starting with this ketone, all right?

So think about starting with this ketone here, so let me go ahead and redraw it. I'm going to draw it in a slightly different way. All right, so that's this ketone right here. And to that ketone, we're psychology essay working memory model to add LDA. So we're going to basics of retrosynthesis a lithium enolate a day at the dentist essay, and once we've basics of retrosynthesis our lithium enolate, then we can add our aldehyde.

So in our second step, we can add our aldehyde in here, so we talked about this in earlier video. So we have documenting a research paper aldehyde as a 4-carbon aldehyde, all right, so we're going to add butanal. And then that's going to give us a, a lithium alkoxide, right? So we need to we need to protonate the alkoxide, so in the workup, we can add some water here. And basics of retrosynthesis would give us our aldol product, so that would give us essay describe a friend, so that is the way to synthesize our aldol products.

Let me go ahead and draw it in here, right, so we would form this. Okay, so basics of retrosynthesis directed aldol addition.
