Title: Electronically mediated selectivity in ring opening of 1-azirines. The 3-z mode: Convenient route to 2-aza-1,3-dienes
Author: Barroso, MT
Kascheres, A
Abstract: Reaction of 1-azirine-3-methylacrylates 1a,b with imidazoles and pyrazoles under mild conditions results in the formation of 2-aza-1,3-dienes 2a-g containing a potential leaving group at the 1-position. Simple alcohols (methanol and ethanol) react similarly with la,b in the presence of sodium carbonate to afford 2h-j. Utilization of 2 in the hetero Diels-Alder reaction with electron-deficient dienophiles is described.
