    Catalytic Enantioselective Synthesis of Flavanones and Chromanones
    摘要:
    The enantioselective synthesis of flavanones and chromanones is described. Bifunctional thiourea catalysts promote an asymmetric oxo-conjugate addition to a beta-ketoester alkylidene in high yields with excellent enantioselectivity (80-94% ee) for aryl and alkyl substrates. Decarboxylation of the beta-ketoester proceeds smoothly in a one-pot procedure to afford the enantioenriched flavanones and chromanones.

    Tryptophan-derived tertiary amine-thiourea catalysts were shown to promote a cascade oxa-Michael–Michael reaction between ethylene β-keto esters and nitroolefins, resulting in the formation of 3,3-disubstituted 4-chromanones bearing a quaternary center in high diastereoselectivity and enantioselectivity. The chromanone products can be readily converted to biologically important fused and spiro tricyclic
