Diels-Alder Flashcards
1
Q
Forms what
A
6 membered rings in one step concerted reaction
2
Q
Cis principle
A
Concerted reaction = stereochemistry is preserved = stereospecific
3
Q
Diene structure
A
Must be able to adopt cis conformation, good diene = always cis and further activated by EDG
4
Q
How is dienophile activated
A
EWG
5
Q
Endo rule
A
Endo product preferred if dienophile substituents have π-bonds in conjugation
6
Q
Product if dienophile doesn’t have conjugating withdrawing group
A
Exo = least sterically hindered
7
Q
Regioselectivity
A
Match most δ+ with most δ-
