Herein we present a library of simple amide derivatives of Cinchona alkaloids in the form of quaternary ammonium salts. The obtained derivatives can be generated very easily and efficiently from inexpensive and commercially available substrates. We tested this class of alkaloids in the alkylation of glycine derivative, carried out under phase-transfer catalyst conditions. The presented hybrid catalysts offer both high reaction yields (up to 97%) and high enantioselectivities of the obtained product (up to 94% ee).
