D-threo-sphinganine, L-erythro-sphinganine and (−)-spisulosine from the higher homologue of Garner'saldehyde prepared from l-aspartic acid is reported. While the starting material contains one of the stereocenters in the target molecules, the other is generated by proline-catalyzed asymmetric α-hydroxylation of the aldehyde function. The two diastereomers of sphinganine are prepared from the same starting
