D-erythro-Sphingosine is synthesized from N-benzoyl-D-glucosamine 2 in a highly regio- and stereo-controlled manner. The key features in the synthesis involve the efficient conversion of compound 2 into the vinyl epoxide 10 and the subsequent SN2′-type reaction with a Grignard reagent in the presence of CuCN to afford the 1-O,2-N-protected sphingosine 11.
Regio- and stereocontrolled synthesis ofD-erythrosphingosine and phytosphingosine fromDglucosamine

D-erythro-Sphingosine (1) and phytosphingosine (2) have been efficiently synthesized from D-glucosamine by utilizing its whole carbon skeleton and functional groups. In this synthetic route, regioselective alkylation of the epoxy-tosylate 9 was achieved with a copper(I)-catalyzed Grignard reagent to give the key intermediate 10, which was converted to both 1 and 2 via regioselective formation of the iodohydrin 11.
