title: Synthesis of D,L beta-aminomethyl derivatives of gamma-(p-chlorophenyl)-tetrahydrofuran-2-one.
abstract: Several new D,L beta-aminomethyl derivatives of gamma-(p-chlorophenyl)-tetrahydrofuran-2-one have been synthesized. The derivatives of D,L beta-aminomethyl-beta-(p-chlorobenzoyl)-propionic acid 2-6 were used as the substrates. These compounds were obtained by the Mannich reaction from acid 1, cyclic secondary amines and formaldehyde. After the reduction with NaBH4, and cyclization, derivatives 2-6 were converted into the appropriate derivatives of tetrahydrofuran-2-one 9-13. Some of the obtained compounds (5, 6, 8, 11 and 12) showed depressant activity against the central nervous system.
