Abstract
A procedure has been developed for the synthesis of ethyl 1-benzoyl-4-chloro-2-phenylpyrrolidine-2-carboxylate and 4-chloro-5-oxo-1,2-diphenyl-, 1-benzoyl-2-(2-benzyloxy-5-chlorophenyl)-4-chloro-, and 1-benzoyl-2-(4-benzyloxyphenyl)-4-chloropyrrolidine-2-carbonitriles in high yields via intramolecular cyclization of the corresponding 2,3-dichloropropionamides under conditions of phase-transfer catalysis.
