We report herein a short and efficient synthesis of benz[e][1,2,4]- or [d][1,2,6]oxadiazepines and benzo[f][1,3,5]triazocines from easily prepared N-aryl iminoesters. The strategy involves a bis-nucleophile reagent (hydroxylamine or guanidine) that promotes a one-step ring closure from the starting functionalized iminoesters.
我们在这里报告了由容易制备的N的短而有效的合成苯并[ e ] [1,2,4]-或[ d ] [1,2,6]恶二氮杂卓和苯并[ f ] [1,3,5]三唑嗪的方法-芳基亚氨基酯。该策略涉及双亲核试剂(羟胺或胍),该试剂从起始的功能化亚氨基酯促进一步闭环。
