Abstract
A process is disclosed for producing an optical active alkoxybenzonitrile derivative in which process a benzonitrile derivative is subjected to condensation reaction with an optical active alcohol. A process is also disclosed for producing an optical active alkoxy benzoic acid derivative in which process a benzonitrile derivative is subjected to condensation reaction with an optical active alcohol and the reaction product thus derived is hydrolyzed. In these processes conversion of an optical active alcohol to tosylate or halide is not required and thus it is possible to produces producing an optical active alkoxybenzonitrile derivative and an optical active alkoxy benzoic acid derivative in a simple and inexpensive manner.
