Asymmetric syntheses of lignans of the dibenzylbutyrolactone, dibenzylbutanediol, aryltetraun and dibenzocyclooctadiene series
摘要:
General procedures are outlined for the asymmetric syntheses of lignans of the dibenzylbutyrolactone, dibenzylbutanediol, aryltetralin and dibenzocyclooctadiene series, from tandem addition products derived from 4-menthyloxybutenolide.

Addition of dithianes, derived from alkyl- and aryl-aldehydes, to (5R)-menthyloxy-2[5H]-furanone followed by quenching with substituted benzylhalides or a benzaldehyde gives enantiomerically pure lignan type compounds in good yields.
