Processos de preparação de diisopinocanfeilcloroborano e de redução de uma cetona proquiral |
| 摘要 |
<p>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.</p> |
