Highly Stable Keto-Enamine Salicylideneanilines

Highly stable NH salicylideneanilines have been prepared by reaction of 1,3,5-triformylphloroglucinol with aniline derivatives. The NH form was confirmed by X-ray crystallographic data, as well as by NMR studies. A convenient one-step synthesis of triformylphloroglucinol is also reported.本研究通过1,3,5-三甲酰基间苯三酚（1,3,5-triformylphloroglucinol）与苯胺衍生物的反应，合成了高度稳定的NH型水杨醛缩苯胺类（NH salicylideneanilines）化合物。其NH型结构通过X射线晶体学数据以及核磁共振（NMR）研究得以确证。本文同时报道了1,3,5-三甲酰基间苯三酚的简便一步合成法。
