A facile and efficient method has been developed for the synthesis of a small library of dibenzo[b,f][1,4]thiazepin-11(10H)-ones via Smiles rearrangement. Compounds were obtained in excellent isolated yields (70%–92%) under metal-free conditions. More specifically, this transition metal-free process relates to an environmentally friendly, economical, and efficient method for preparing benzoic-fused
已经开发了一种通过Smiles重排合成小的二苯并[ b,f ] [1,4] thiazepin-11(10 H)-ones小型文库的简便有效方法。在无金属条件下,化合物的分离产率极高(70%–92%)。更具体地说,这种无过渡金属的方法涉及制备苯并稠合的七元内酰胺的环保,经济和有效的方法。
