Abstract
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, vestitol and medicarpin, as well as isoflavane analogues were readily prepared with good to excellent enantioselectivities.
