Synthesis of sphingosine relatives, VII. Synthesis of anti‐ulcerogenic cerebrosides isolated from Tetragonia tetragonoides

The synthesis of (2S,3R,4E,8E,2′R)‐1‐O‐(β‐D‐glucopyranosyl)‐N‐(2′‐hydroxyhexadecanoyl)‐4,8‐sphingadienine (1a) and its (8Z) isomer 1b was accomplished by employing (R)‐2‐aminohexadecanoic acid, D‐glucose, and (S)‐serine as chiral sources.
