✦ Synopsis

Easily available D-(+)-camphor-derived chiral mercapt*alcohols 2 and 3 were employed for catalytic asymmetric borane reduction of aromatic ketones. Moderate enantioselectivities with e.e. 20.2-72.1% were obtained with 10 mol% catalyst. Opposite asymmetric induction was achieved' when mercaptc-alcohols 2 and 3 were used.
