New perspectives of carbo- and hetero-1,3-dienes in organic synthesis

Abstract

The preparation and reactivity of 4-amino-l-azadienes and electronically neutral 2-azadienes is reported. The suitability of the 1-azadiene system for the synthesis of five-, six-, seven-, and eight-membered as well as the synthetic utility of 2-azadienes through [4+2] cycloadditions is presented. © 1990, IUPAC.
