An efficient two‐step procedure for the preparation of a new type of 1H‐isoindoles, i.e., N‐(3‐alkyl‐1‐aryl‐ or 1,3‐diaryl‐1H‐isoindol‐1‐yl)‐O‐methylhydroxylamines 5, from readily available aryl(2‐bromophenyl)methanones 1 has been developed. Aryl(2‐bromophenyl)methanone O‐methyloximes 2, derived from the corresponding ketones, were treated with BuLi in Et2O at 0° to generate novel lithium compounds
制备新型1 H-异吲哚的有效两步程序,即N-(3-烷基-1-芳基或1,3-二芳基-1 H-异吲哚-1-基)-O -methylhydroxylamines 5,从容易获得的芳基(2-溴苯基)甲酮1已经研制成功。芳基(2-溴苯基)甲酮Ô -methyloximes 2,从相应的酮衍生的,用BuLi的处理的Et 2在0°O以产生新颖的锂化合物,芳基(2-lithiophenyl)甲酮ø -methyloximes 3,其被允许与腈反应生成所需的产物5 以中等至中等的收益率。
