Abstract

The first total synthesis of stereochemically pure resolvin D3 and aspirin-triggered resolvin D3 is reported. These enzymatic metabolites of docosahexaenoic acid (DHA) have potent anti-inflammatory and pro-resolving actions. The convergent synthetic strategy is based on enantiomerically pure starting materials, and it is highly stereocontrolled.
