The enantioselective hydroboration of racemic allenylsilane (±)-4 with (dIpc)2BH 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 C provides (E)-δ-silyl-anti-homoallylic alcohols in 71-89% yield and with 93-96% ee.
