A novel route to 2,3-substituted benzo[b]thiophenes by intramolecular radical cyclization of polarized ketene dithioacetals derived from o-bromoarylacetonitriles or the corresponding 3-(methylthio)-3-alkyl/aryl/heteroaryl analogues has been reported.
据报道，通过分子内自由基环化由邻溴芳基乙腈衍生的极化乙烯酮二硫代缩醛或相应的3-(甲硫基)-3-烷基/芳基/杂芳基类似物，可得到一种合成2,3-取代苯并[b]噻吩的新方法。
