Predict the products of the following proposed Diels–Alder reactions. (d)

Accepted Answer

Hey everyone. Let's do this problem and says provide the final products expected from the deals alder reaction given below. So let's review what is a deal's alder reaction, it's a very popular cyclo addition reaction where we have four plus two cyclo edition, That is four pi bonds plus to buy bonds. And that will form a six member id ring product. So let me show you an example of this type of reaction. So in our deals older reaction, we always have a dying Which has our four pi electrons right to four. And we have our Diana file. I'll just give you an example of one in the Diana file or lover of dying's is an electron poor al keen or AL kind. So that makes it prone to react with the dying. And this again has at least two pi electrons that can have more right. For example if it's an AL kind. But we're only reacting the two pi electrons with the four pi electrons to make our new ring. And this reaction occurs with heat. So it will form this product A six member ring. And we're converting these two pi bonds into two sigma bonds and a new double bond in between where those double bonds were. And we showed this mechanism with three simple arrows. 123 going from our Diana file to our dying scooting over one double bond in our dying and then that second double bond and are dying back to the Diana file. And another characteristic about deals all the reactions is that they are stereo specific. So the reaction is sin And the configuration of the diana file is retained in the product. So if we have assist diana file, it will produce assist product. If we have a trans diana file, it will produce a trans product. So let's apply this to our reaction given here. So we have our dying and our diana file which is an al cane. So let's draw our three arrows going from our diana file to our dying, shifting over in our dying and then from our dying back to our dying a file. So we will have a bicycle compound because our dying is already a ring. So we've created a new double bond in our dying And there are the five carbons from our dying. And then we have the two carbons from our Diana file and we have to add the substitue into groups to those the four alga hide groups. C H O C H O C H O C H O. And that wasn't all keen. So now there is no pi bonds there. So that is the expected product for this deals older reaction, which makes see the correct answer for this problem. That's it for this one. I hope this video is helpful
