C-hex-2-enopyranosides) have been obtained in excellent yield and stereoselectivity from the trimethylsilyl triflate (Me 3SiOTf) catalyzed reaction of trichloroacetimidate derivative 2 with silylated nucleophiles such as allyl and propargyl silanes and silyl enol ethers. a Dedicated to Prof. Joachim Thiem on the occasion of his 60th birthday.
通过三氟乙磺酸亚甲基三酸酯(Me 3SiOTf)催化三氯乙酰亚胺酸酯衍生物2与甲硅烷基化的亲核试剂(如烯丙基和甲基)的三甲基甲硅烷基三甲酸酯(Me 3SiOTf),以优异的收率和立体选择性获得了多种功能化的伪糖基C-糖苷(C-伪糖基或C-hex-2-enopyranosides)。炔丙基硅烷和甲硅烷基烯醇醚。献给Joachim Thiem教授60岁生日之际。
