A short synthetic strategy for 3,6-disubstituted-N-2-thienyl/aryl-indoles, involving reaction of substituted 2,4-difluoro/dichloro-styrene epoxide with substituted 2-formylaminothiophenes or substituted N-formylanilines in the presence of a base followed by treatment with an acid, has been developed. The method was applied for the synthesis of a number of indoles with a variety of substituents at 1
一种3,6-二取代的-N -2-噻吩基/芳基吲哚的短合成策略,涉及取代的2,4-二氟/二氯-苯乙烯环氧化物与取代的2-甲酰氨基噻吩或取代的N-甲酰苯胺在a的存在下的反应。已开发出碱,然后用酸处理。该方法用于合成在吲哚部分的1、3和6位具有多个取代基的许多吲哚。
