If the chiral amino alcohol is incorporated into polystyrene, a chiral polymeric reducing agent is obtained. Acetophenone O-methyloxime was reduced by such a polymeric borane complex to give optically active 1-phenylethylamine with 99% ee35 36 With borane-tetrahydrofuran and 1 mol% of the chiral amino alcohol (lS,3S,5S)-(a,a-diphenyl)hydroxymethyl-2-azabicy-clo[3.3.0]octane (7), (7 )-1-phenylethylamine can be synthesized from acetophenone O-methyloxime in 64% yield with 17% ee37.
