Total synthesis of Resolvin D1, a potent anti-inflammatory lipid mediator

The total synthesis of Resolvin D1, a potent endogenous anti-inflammatory lipid mediator derived from docosahexaenoic acid, has been achieved. The chiral hydroxy-groups at C7, C8 and C17 were obtained via a chiral pool strategy from 2-deoxy-d-ribose. Wittig reactions followed by a modified Pd0/CuI Sonogashira coupling and Zn(Cu/Ag) cis-reduction completed the total synthesis of Resolvin D1.
