    Abstract

    The formal total synthesis of (-)-physostigmine via the chiral malonic acid mono-ester ((R)-2-(2-chlorophenyl)-2-methoxycarbonylpropanoic acid, 99% ee) newly prepared by the pig liver esterase (PLE) mediated asymmetric hydrolysis of the corresponding di-ester is described. The CuI-mediated intramolecular aryl amidation under modified Buchwald's conditions is a key reaction to constructing the oxindoline core in the target.
