摘要

Cinchona ammonium salts from cinchonine, cinchonidine, quinine and quinidine alkaloids have been anchored to polymers and used as phase-transfer catalysts in the enantioselective alkylation of N-diphenylmethylene glycine esters to afford enantioenriched a-amino acid derivatives. These supported catalysts can be separated from the reaction medium and reused, being promising from an industrial viewpoint.
