title: Synthesis and preliminary pharmacological investigation of the central action of derivatives of 3-aminomethyl-5-(p-chlorophenyl)-tetrahydrofuran-2-one and 2-aminomethyl-4-(p-chlorophenyl)-4-hydroxybutyric acid.
abstract: Using 3-cyano-5-(p-chlorophenyl)-tetrahydrofuran-2-one 4, 3-aminomethyl derivatives of 5-(p-chlorophenyl)-tetrahydrofuran-2-one were synthesized. The starting material under alkaline hydrolysis yielded 5-(p-chlorophenyl)-tetrahydrofuran-2-one-3-carboxylic acid 5, which was transformed, via an acid chloride, into amide 6. From acid 5 by aminomethylation compounds 7-12 were obtained. Some of them (7, 8, 12) in reactions of ammono-, amino-, and hydrazinolysis yielded corresponding derivatives of 2-aminomethyl-4-(p-chlorophenyl)-4-hydroxybutyric acid 13-20. In pharmacological tests compounds 10 displayed analgesic activity while compounds 2 and 3 revealed anxiolytic properties.
