New routes to cyclic and spirocyclic sulfides involve aldol reactions of dithioesters or chemoselective Mitsunobu reactions on diols to give 2-hydroxyalkylsulfides 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.

New routes to cyclic and spirocyclic sulfides involve aldol reactions of dithioesters or chemoselective Mitsunobu reactions of 1,n-diols to give 2-hydroxyalkyl sulfides with a terminal SH group. Treatment with acid gives unrearranged cyclic sulfides, or by rearrangement with PhS-migration, spirocyclic thiolanes and allylic sulfides in almost quantitative yield. We comment on the effect of the chain
