So far, I understand the mechanism of the Diels Alder reaction and am able to correctly predict the product of some slightly complex examples.
However, it seems that in some examples, a racemic mixture is formed, whereas in others that's not the case.
I have basic understanding of the Endo Rule (endo product favored over exo product), but have trouble with the stereo chemistry involved.
I also know that the symmetry of the diene and dienophile has to do with it, but can't seem to find a consistent pattern.
Any help would be appreciated.
