After a brief review of the literature on asymmetric reduction of prochiral ketones using polymer-supported catalysts or reagents some new results in this field are presented. In particular asymmetric reduction is reported here using (1) chiral oxazaborolidines as catalyst and BH3 as reducing agent,

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-alcoh
