Asymmetric hydroboration of appropriate alkenes with diisopinocampheylborane (Ipc2BH) or monoisopinocampheylborane (IpcBH2) produces intermediates that readily eliminate α-pinene on treat- ment with acetaldehyde, providing a direct, convenientroute to chiral boronicesters of high enantiomeric purities. Mixed chiral trialkylboranes, readily prepared by stepwise hydroboration of appropriate alkenes
