New routes to cyclic and spirocyclic sulfides involve aldol reactions of dithioesters or chemoselective Mitsunobu reactions on diols to give 2-hydroxyalkyl sulfides with a terminal SH group. Treatment with acid gives cyclic sulfides, or by rearrangement with PhS migration, spirocyclic sulfides or allylic sulfides in good yield.
产生环状和螺环硫化物的新途径涉及二硫酯的醛醇缩合反应或二醇上的化学选择性的Mitsunobu反应,生成带有末端SH基团的2-羟烷基硫化物。用酸处理可得到环状硫化物,或通过PhS迁移进行重排,可得到高产螺环硫化物或烯丙基硫化物。
