The enantioselective hydroboration of racemic allenylsilane (+/-)-4 with ((d)Ipc)(2)BH proceeds via enantiodivergent pathways to give vinylborane 11 and crotylborane intermediate (S)-E-5. Subsequent crotylboration of aldehyde substrates with (S)-E-5 at -78 degrees C provides (E)-delta-silyl-anti-homoallylic alcohols in 71-89% yield and with 93-96% ee.
