Abstract:Maresin 1 (with the 7R carbon) and (7S)-maresin 1 were synthesized stereoselectively. The conjugated triene system was constructed by Pd-catalyzed coupling of the trans cis-dienylborane (the C10–C22 part) with the trans vinyl iodide corresponding to the C1–C9 part. The stereogenic centers at C7 and C14 were created by Ru-catalyzed asymmetric reduction of ketone and asymmetric epoxidation/kinetic resolution of the racemic alcohol, respectively.
Keywords:Maresin 1  Stereoselective synthesis  Suzuki&ndash  Miyaura coupling  Lipid mediator  Docosahexaenoic acid
