Asymmetric borane reduction of α-hydroxy ketones protected with a tetrahydropyranyl (THP) group catalyzed by Corey's CBS reagent using N-phenylamine–borane complexes as the hydride source provided the corresponding terminal 1,2-diols with a very high enantiomeric excess.
Corey's CBS试剂使用N-苯胺-硼烷络合物作为氢化物源,催化被四氢吡喃基(THP)保护的α-羟基酮的不对称硼烷还原,提供了相应的末端1,2-二醇很高的对映体过量。
