  Enantiodivergent hydroboration reactions of a racemic allenylsilane with diisopinocampheylborane and Curtin–Hammett controlled double asymmetric crotylboration reactions of (S)-E-α-phenyldimethylsilyl(ddiisopinocampheyl)-crotylborane

  摘要：

  The enantiodivergent hydroboration reactions of racemic allenylsilane (+/-)-4 with ((d)Ipc)(2)BH and subsequent crotylboration of achiral aldehydes with the product crotylborane (S)-E-5 at -78 degrees C provide (E)-delta-silyl-anti-homoallylic alcohols 6 in 71-89% yield and with 93-96% ee. Intriguingly, mismatched double asymmetric crotylboration reactions of enantioenriched chiral aldehydes 20 with (S)-E-5 proceed under Curtin-Hammett control to give anti-beta-hydroxylcrotylsilanes 24 as the only products.

  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.
