Total synthesis of the macrophage derived anti-inflammatory lipid mediator Maresin 1
摘要:
The total synthesis of Maresin 1, an endogenous macrophage pro-resolving lipid mediator derived from docosahexaenoic acid, has been achieved. The chiral hydroxy-group at C7 was obtained via a Jacobsen hydrolytic kinetic resolution of a terminal epoxide whereas the center at C14 arises from a chiral pool strategy starting from 2-deoxy-D-ribose. Pd-0/Cu-1 Sonogashira coupling of the two key fragments and 2n(Cu/Ag) reduction completed the total synthesis of Maresin 1. (C) 2012 Elsevier Ltd. All rights reserved.

The first totalsynthesis of the potent anti-inflammatorylipidmediator Maresin 2 derived from docosahexaenoic acid, has been achieved. The chiral hydroxy-groups at C13 and C14 were obtained via a chiral pool strategy from 3,4-O-isopropylidene-2-deoxy-d-ribose. Wittig reactions and acetonide cleavage followed by mild ester hydrolysis afforded Maresin 2.
