enantioselective synthetic route to the bicyclic tetraene ester 3, a key intermediate for the synthesis of the naturally occurring adenosine diphosphate transport inhibitor atractyligenin (2). The success of this route depended on the extension of the oxazaborolidine-catalyzed (CBS) reduction of an achiral β-stannyl-substituted α,β-enone (6c) to form a chiral allylic alcohol and further steps to effect simultaneous
