3.5.2 Reactions of Alkylboranes
3.5.2.1 Synthesis of Alcohols

The transformation of alkenes to alcohols proceeds with complete retention of configuration at the boron-bearing carbon (Scheme 2).

Scheme 2

Asymmetric hydroboration of alkenes can be carried out using chiral boranes with excellent enantioselectivity (Scheme 3).
