Synthesis of sphingosine relatives, X. Synthesis of (2S,3R4E)‐1‐O‐(β‐ D ‐glucopyranosyl)‐N‐[30′‐(linoleoyloxy)triacontanoyl]‐4‐icosasphingenine, a new esterified cerebroside isolated from human and pig epidermis

Abstract (2S,3R,4E)‐1‐O‐(β‐D‐Glucopyranosyl)‐N‐[30′‐(linoleoyloxy)triacontanoyl]‐4‐icosasphingenine (1) was synthesized from D‐glucose, L‐serine, 15‐pentadecanolide, and linoleic acid. The high‐field 1H‐NMR spectrum of 1 was identical with that of the esterified cerebroside isolated from human and pig epidermis.
