A nickel-catalyzed tandem reaction involving cyclic esterification/C–S bond formation has been developed. Starting from samples containing 3-(2-hydroxy-phenyl)-acrylic acids with 2-halide-benzenethiols, versatile biologically active 5-oxa-11-thia-benzofluoren-6-one compounds were efficiently synthesized in good to high yields. This new methodology provides an economical approach toward C–S bond formation
已经开发了涉及环状酯化/C-S键形成的镍催化串联反应。从含有 3-(2-羟基-苯基)-丙烯酸和 2-卤化物-苯硫醇的样品开始,高效地合成了具有良好至高产率的多功能生物活性 5-oxa-11-thia-benzofluoren-6-one 化合物。这种新方法为 C-S 键的形成提供了一种经济的方法。
