Abstract

The reversal phenomenon of enantioface selectivity in the asymmetric addition of diisopropylzinc to aldehydes was observed by mixing two chiral β-amino alcohol catalysts. The opposite enantiomeric product was formed on using a mixture of two chiral catalysts that possess individual enantioselectivity.
