Two unprecedented and complementary synthetic strategies for S- and C-difluoromethylation of 2-substituted benzothiazoles have been developed by taking advantage of the remarkably different reactivity of CF2H– and 2-PySO2CF2– nucleophiles. A variety of structurally diverse difluoromethyl 2-isocyanophenyl sulfides and 2-difluoromethylated benzothiazoles were synthesized with these two new synthetic
利用 CF 2 H和 2 - PySO 2 CF 2亲核试剂的显着不同反应性,开发了两种前所未有的互补合成策略,用于 2-取代的苯并噻唑的 S-和 C-二氟甲基化。用这两种新的合成方案合成了多种结构多样的二氟甲基 2-异氰基苯硫醚和 2-二氟甲基苯并噻唑。
