摘要：

The (L)-threo-N,N-dibenzyl sphingosine was prepared in two steps from the serinal derivative 1 by diastereoselective alkenylation with pentadec-l-enyl(ethyl)zinc and deblocking. (D)-erythro-N,N-Dibenzyl sphingosine was also prepared in two steps from 1 by a highly diastereoselective alkynylation with pentadecynyl magnesium bromide and subsequent stereoselective LAH reduction.
