A synergetic copper/photoredox catalyzed ATRA of styrenes and thiosulfonates is developed. Besides aryl ethylenes, the challenging α-substituted styrenes were employed to construct the benzylic quaternary carbon centers. Owing to the mild conditions as well as the high level of substrate compability, this ATRA could be applied to derivatize bioactive natural products in late stage, and to install fluorophores
开发了协同铜/光氧化还原催化苯乙烯和硫代磺酸盐的ATRA。除芳基乙烯外,具有挑战性的α-取代的苯乙烯还用于构建苄基季碳中心。由于条件温和以及高水平的底物相容性,该ATRA可以用于后期生物活性天然产物的衍生化,并可以在整个烯烃中安装荧光团。机理研究表明,磺酰基是转化的关键中间体。
