The introduction of an acetylamino group at the 2′-position in the aniline ring of a naphthoquinone methide dye produced a red shift with a large increase in the molecular extinction coefficient in CHCI3 solution, and an intramolecular ring-closure reaction of the compound under alkaline conditions gave a new blue dye; the stereochemistry of this chromophoric system was determined by X-ray analysis
在萘醌甲基化物染料的苯胺环的2'-位引入乙酰氨基会产生红移,在CHCI 3溶液中的分子消光系数大大增加,并且化合物的分子内闭环反应在碱性条件下产生了新的蓝色染料;通过X射线分析确定该发色系统的立体化学。
