The facile synthesis of a series of 4-acyloxy-2-azabuta-1,3-dienes by the O-benzoylation and O-acetylation of the anions of the readily accessible monoimines of phenyl glyoxal, diacetyl, benzil, and 1-phenyl-propan-1,2-dione is described. This route provides easy access to 2-azabuta-1,3-dienes with substituents other than aryl groups on C-1, C-3, and C-4 of the diene skeleton.
描述了一系列4-酰氧基-2-氮杂丁-1,3-烯的简便合成,通过对容易获得的苯基乙醛单亚胺、二乙酰、苯基和1-苯基丙烯-1,2-二酮的负离子进行O-苯甲酰化和O-乙酰化。这条路线提供了便捷的途径,以获取在烯烃骨架的C-1、C-3和C-4位置上具有芳基以外取代基的2-氮杂丁-1,3-烯。
