The reaction of N-(3-phenylpropionyloxy)phthalimide (1a) and N-tosyloxy (5a,b) derivatives with nucleophiles was examined and found to give the products via Lossen-type rearrangement. In order to obtain the scope of this reaction mechanism, further studies the reaction of several N-sulfonyloxyimide derivatives with various nucleophiles under similar conditions were carried out and found to afford the
研究了N-(3-苯基丙酰氧基)邻苯二甲酰亚胺(1a)和N-甲苯磺酰氧基(5a,b)衍生物与亲核试剂的反应,发现它们通过Lossen型重排产生了产物。为了获得该反应机理的范围,在相似条件下进一步研究了几种N-磺酰氧基酰亚胺衍生物与各种亲核试剂的反应,发现它们以高收率提供了相应的相同类型的产物。
