    Abstract: PURPOSE: A method for synthesizing bifunctional cinchona alkaloid catalyst is provided to ensure low toxicity, and chemical stability, and synthesize chiral hemiester having various structures in a short time. CONSTITUTION: A bifunctional cinchona alkaloid catalyst is denoted by chemical formula 1 or 2. A chiral hemiester is produced by reacting a prochiral or meso-cyclic acid anhydride with nucleophile in organic solvent under the presence of the bifunctional cinchona alkaloid catalyst. The nucleophile is alcohol or thiol. The organic solvent is dimethoxyethane, ethylvinyl ether, methyl t-butyl ether, diethyl ether, diisopropyl ether, tetra hydro furan or dioxane.
