Abstract
D-erythro-sphinganine 1 and L-threo-sphinganine 2 have been prepared in the enantiomerically pure form by the chirospecific manner. Key intermediates, 2-amino-3-hydroxy-4-pentenoates 8 and 12, were obtained from L-glucono-1,5-lactone and L-gulonic acid g-lactone via a simultaneous dealkoxyhalogenation.
