Abstract: | Synthesis of (+)-11-hydroxyhexadecanoic acid-O-(4-O-α-L-rhamnopyranosyl)-α-L- rhamnopyranoside showed that muricatin B from Ipomoea muricata does not contain the proposed β- but an α-linked dirhamnoside moiety. This is the first reported synthesis of a naturally occurring O-glycoside of a long chain hydroxy-fatty acid. |
