    • The E and Z isomers of ACPs 10 have opposite absolute configurations. The E/Z ratio of (E)-10 is 93:7, and the absolute configuration of (E)-10 is S, whereas (Z)-10 is R-configured. Each geometric isomer was formed with an enantiomeric ratio of > 99:1. Accordingly, in the rhodium-catalyzed hydrosilylation reaction of enantiomerically pure 10 [(E,S)-10/(Z,R)-10 = 93:7], E and Z homoallylsilanes 14 were formed with the same E/Z ratio as that of the starting material [(E,R)-14/(Z, S)-14 = 93:7]. After chromatographic separation of the two isomers, they were each subjected to hydrogenation of the double bond, followed by oxidation. The corresponding saturated alcohols containing a quaternary center were obtained in quantitative yield with an enantiomeric ratio similar to that of the starting material (Scheme 7).
