This paper reports the tandem reaction strategy of the Passerini/Staudinger/aza-Wittig reaction based on the in situ capture of isocyanides. According to this strategy, isocyanides are synthesized in situ and immediately work as the substrate for the Passerini reaction and postmodification tandem reaction in one pot. In addition, two types of new compounds, 5-oxo-3,5-dihydrobenzo[e][1,4]oxazepines
本文基于异氰酸酯的原位捕获,报道了Passerini / Staudinger / aza-Wittig反应的串联反应策略。根据这一策略,异氰化物可在原位合成,并立即用作一罐中Passerini反应和后修饰串联反应的底物。此外,还使用以下方法合成了两种新型化合物:5-氧代-3,5-二氢苯并[ e ] [1,4]氧氮杂卓和6-氧代-5,6-二氢-2 H -1,4-恶嗪。一站式反应策略,其中包括五步转化。
