A chemoenzymatic access to d- or l-sphingosines is presented comprising of a totalsynthesis of the l-threo-isomer and formal syntheses of the other three isomers. Key to the development of a general synthetic strategy has been the use of enantiocomplementary hydroxynitrile lyases (Hnls) to yield an enantiomeric pair of starting materials. The (S)-Hnl from Hevea brasiliensis has been used to prepare
