Reported herein is a general approach to optically active isoflavanes based on a chiral amine-catalyzed [4 + 2] asymmetric annulation of o-quinone methides and aldehydes. A number of naturally occurring isoflavanes, including equol, sativan, isosativan, v

(3S)-2',7-Dihydroxy-4'-methoxyisoflavan serves as bifunctional nucleophile at C-5' and C-6, when condensed with the carbocation generated at C-11a of its (6aS,11aS)-3-hydroxy-9-methoxypterocarpan analogue under mild acid conditions or by photolysis, to fo
