Abstract
One aspect of the present invention relates to quinine-based and quinidine-based catalysts. Another aspect of the present invention relates to a method of preparing a chiral, non-racemic compound from a prochiral electron-deficient alkene, comprising the step of: reacting a prochiral electron-deficient alkene with a nucleophile in the presence of a catalyst; thereby producing a chiral, non-racemic compound; wherein said catalyst is a derivatized quinine or quinidine.
