The first total synthesis of the lipid mediator MaR1n-3 DPA (5) has been achieved in 12% overall yield over 11 steps. The stereoselective preparation of 5 was based on a Pd-catalyzed sp3-sp3 Negishi cross-coupling reaction and a stereo controlled Evans-Nagao acetate aldol reaction. LC-MS/MS results with synthetic material matched the biologically product 5. This novel lipid mediator displayed potent pro-resolving properties stimulating macrophage efferocytosis of apoptotic neutrophils.
