A novel and efficient approach to the synthesis of benzimidazo[2,1-b]thiazoline derivatives has been developed through an addition/cyclization/intramolecular oxidative C–H functionalization process. A variety of alkylene benzimidazo[2,1-b] thiazolines were conveniently assembled from the reaction of aryl isothiocyanate and propargylic amine in the presence of Cu(OAc)2 and PIFA at room temperature.
通过加成/环化/分子内氧化C–H官能化过程,已开发出一种新颖且有效的合成苯并咪唑[2,1- b ]噻唑啉衍生物的方法。在室温下,在Cu(OAc)2和PIFA存在下,由异硫氰酸芳基酯和炔丙基胺反应可方便地组装各种亚烷基苯并咪唑并[2,1- b ]噻唑啉。该产物可以进一步转化为取代的苯并咪唑并[2,1- b ]噻唑衍生物。
