摘要: The present invention relates to an improved process for the in situ preparation of diisopinocampheylchloroborane which comprises reacting sodium borohydride and boron trichloride with .alpha.-pinene. The diisopinocampheylchloroborane thus obtained may be used, without isolation, to reduce prochiral ketones to their corresponding alcohols in high optical purity.
