acyclic vinyl sulfones having a suitably positioned leaving group reacted with externally delivered carbon, nitrogen, oxygen, and sulfur nucleophiles to afford a series of five-membered carbocycles and heterocycles in a diastereoselective fashion. This diversity-oriented synthetic method generates a wide range of chirally pure cyclic compounds from easily accessible starting materials and reagents
具有适当位置的离去基团的戊糖基和己糖基无环乙烯基砜与外部传递的碳、氮、氧和硫亲核试剂反应,以非对映选择性方式提供一系列五元碳环和杂环。这种以多样性为导向的合成方法可以从容易获得的起始材料和试剂中生成范围广泛的手性纯环状化合物。
