Reactions of 1-Aza-1,3-dienes

High to complete stereoselectivities were observed in the reactions of 1-aza-l,3-dienes with appropriate alkenes. Concerted as well as two-step mechanisms have been suggested. 

Reactions of Chiral I-Aza l, 3-dienes with Achiral Dienophiles 

Thermal reactions of a,p-unsaturated SAMP hydrazones with reactive, electron-deficient alkenes, e.g. A-methylmaleimide, proceed highly stereoselective.
