Enantioselective Catalytic Borane Reduction of Prochiral Ketones: Synthesis and Application of New Rigid β-Amino Alcohols with a Cycloalkanol Subunit
摘要:
Enantiocontrolled reduction of prochiral ketones with borane in the presence of new enantiomerically pure bi- and tricyclic beta-sec-amino alcohols 2-5 as stereodifferentiating catalysts afforded the optically active corresponding secondary alcohols in moderate to excellent (up to 98 % op) optical yields.
