Abstract :Full details of an enantioselective total synthesis of 8-O-4`-neolignan perseal B are presented for the first time. The synthesis was achieved in 8 steps from vanillin and involved the asymmetric dihydroxylation reaction using AD-mix-a to give the key intermedium insert ignore into journalissuearticles values(1S,2S);-1-insert ignore into journalissuearticles values(4-insert ignore into journalissuearticles values(benzyloxy);-3-methoxyphenyl);propane-1,2,3- triol, and the Mitsunobu reaction between phenylpropanoid and vanillin formed perseal B. The synthetic method of perseal B exhibits a new route for 8-O-4`-neolignan.Keywords : Neolignans, perseal B, enantioselective synthesis
