An unexpected access to a new sphingoid base containing a vinylsulfide unit is described. The process involves the 'one-pot' regioselective opening of an epoxide with a thiolate, followed by intramolecular acyl transfer, base-promoted elimination, and final hydrolysis. Excess sodium hydride and high dilution conditions are required for optimal yields. The process is amenable to a variety of thiolates
