Total Syntheses of the Metabolites of Schizandrin

The total syntheses of the metabolites of schizandrin were achieved.The tetracyclic lactone intermediates (13a-e) were prepared in optically pure form by the oxidative coupling reaction of the corresponding 3-benzyl-2-benzylidenebutyrolactones.Mukaiyama hydration of 13b afforded hydroxylactone (14), which was converted into SZ-M3 (4).The introduction of C6,7-diol moiety, which is common to the metabolites (4-11), was carried out by the successive double bond migration to 15a-e, lactone ring reduction ot the allylic diols (32a-e), and glycol formation.Then, reduction of the mesylates 33 completed the syntheses of the metabolites.
