The first total syntheses of enantiomerically pure (+)- ipomeamarone and its enantiomer (−)-ngaione were achieved. From optically pure sec,sec-1,3-diol 6 obtained through enantio differentiating hydrogenation, 11a consisting of sec,tert-1,3-diol was prepared using a novel stereocontrolled hydrogen abstraction/olefin addition process.

Total syntheses of (+)-ipomeamarone and (−)-ngaione were achieved by using newly found stereoselective hydride transfer/olefinaddition process, and syn and anti hydride additions to optically active bicyclic acetal.
