total synthesis of Resolvin E1 (RvE1), a naturally occurring small molecule mediator of inflammation resolution, is reported. Two routes are presented, both modular and convergent in nature, with an excellent control of all stereocenters. The C12- and C18-hydroxy groups are derived from (S)-glycidol while the C5-hydroxy group is installed via enantioselective reduction of a ketoneprecursor. Both the
