Ninhydrin undergoes an unprecedented condensation reaction with various 2-aminobenzamide derivatives in boiling water to afford 11a-hydroxy-11,11a-dihydrobenzo[e]indeno[2,1-b][1,4]diazepine-10,12-dione derivatives. These hitherto unreported products are easily isolated in high yield by a simple filtration step. An interesting “ortho effect” was observed in the condensation reaction of ninhydrin with
茚三酮与各种2-氨基苯甲酰胺衍生物在沸水中进行空前的缩合反应,得到11a-羟基-11,11a-二氢苯并[ e ]茚满[2,1- b ] [1,4]二氮杂-10,12-二酮衍生物。这些迄今未报道的产物可通过简单的过滤步骤轻松地以高收率分离。与2-氨基-茚三酮的缩合反应中观察到一个有趣的“邻位效应” Ñ具有原-phenylbenzamide衍生物-取代基在Ñ苯基部分,其中相应的期望3'-苯基-1' ħ -螺[茚-2,2'-喹唑啉] -1,3,4-'(3' ħ获得)-triones。
