The first regiospecific synthesis of the 2,3-dihydrothieno[2,3-b]thiophene ring system was achieved using an intramolecular Michael addition in the key cyclization step. This strategy represents a novel and potentially general method for dihydrothiophene and dihydrothiophene S,S-dioxide annellation.
在关键环化步骤中使用分子内迈克尔加成法实现了2,3-二氢噻吩并[2,3- b ]噻吩环系统的第一个区域特异性合成。该策略代表了用于二氢噻吩和二氢噻吩S,S-二氧化物环合反应的新颖且潜在的通用方法。
