Chiral isosteviol-derived tertiary amine-thiourea was proven to be effective in catalyzing the asymmetric conjugate addition between α-substituted cyanoacetate and maleimides. Diverse succinimides bearing vicinal quaternary-tertiary stereocenters were obt

The asymmetric conjugate addition of α-substituted cyanoacetates to N-substituted maleimides has been developed. A number of cinchona alkaloids and amine thioureas were evaluated as catalysts. Takemoto's catalyst was found to be the most efficient for the
