The diene, on the other hand, is relatively electron rich. And this is the general definition of the endo product pertaining to cyclic and acyclic dienes: The exo product is formed when the electron-withdrawing group of the dienophilie is pointing away from the π electrons of the diene: Notice that in the exo product, the two groups of the diene and the dienophile are in trans geometry. Diels Alder practice - Answers.pdf - Diels Alder Reactions Worksheet Predict the major product of the following reactions. Show product stereochemistry | Course Hero.

This on the left, this is a diene, but notice that it has an interesting confirmation. This occurs due to the concerted bonding of two independent pi-electron systems. The Diels-Alder reaction is a cycloaddition of a 4 pi + 2 pi (diene + dienophile) system that forms a more stable product due to the fact that the sigma bonds created are more stable than the pi bonds destroyed. Definition & Mechanism Quiz. This is a Diels-Alder reaction; these reactions happen between a nucleophilic diene, shown in blue below, and an electrophilic dienophile, in green.
