Asymmetric 1,4-additions to γ-menthyloxybutenolides. (part II)1 enantioselective synthesis of lignan type compounds.
摘要:
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.
