Direct aldol reactions catalyzed by organocatalyst derived from 2-amino-2 '-hydroxy-1,1 '-binaphthyl

The direct aldol reactions. catalyzed by organocatalyst derived from 2-amino-2'-hydroxy- 1,1'-binaphthyl were studied. Up to 99% yield was obtained for acetone. Up to 99 : 1 anti : syn selectivity and 89% enantioselectivity were obtained for cycloalkanones.
