A novel class of chiral phase transfer catalysts was synthesized conveniently from cinchona alkaloids and 2-(chloromethyl)benzimidazole. Using these new catalysts (10 mol%), enantioselective alkylations of N-(diphenylmethylene)glycine tert-butyl ester were efficiently carried out with various alkyl halides, and the chemical yields were up to 85% with the ee of the products up to 95%.

Key words: chiral phase transfer catalyst, cinchona alkaloid, enantioselective alkylation
