(2S,3S,4E)-2-AMINOOCTADEC-4-ENE-1,3-DIOL;L-THREO-SPHINGOSINE (D18:1)

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The azidosphingosine was then reacted with hydrogen sulfide in pyridine (see Schmidt, Liebigs. Ann. Chem., 663-667 (1988) and U.S. Pat. No. 4,937,328, incorporated herein by reference) to yield L-threo-sphingosine. ##STR10##
