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
