homochiral 1-norbornanesulfenic and sulfonic acid derivatives 2–7, as well as the sulfonic acids 8, are easily synthesised starting from 2-methylene-1-norbornylthiotriflates 1. This new class of homochiral bridgehead thiosulfonates was prepared by us from naturally occurring (+)-camphor and (−)-fenchone. Nucleophilic substitution at the sulfenyl sulfur atom is the key step for this synthetic strategy
新纯手性1- norbornanesulfenic和磺酸衍生物2 - 7,以及作为磺酸8,容易合成从2-亚甲基-1- norbornylthiotriflates开始1。此类新的同型手性桥头硫代磺酸盐是由我们从天然存在的(+)-樟脑和(-)-芬酮制备的。在亚硫基硫原子上的亲核取代是该合成策略的关键步骤。
