摘要:
4-(Polyalkoxyphenyl)-2-pyrrolidones of the formula ##STR1## wherein R.sub.1 and R.sub.2 each are hydrocarbon of up to 18 carbon atoms at least one being other than methyl, a heterocyclic ring, or alkyl of 1-5 carbon atoms substituted by halogen, OH, COOH, alkoxy, alkoxycarbonyl or an amino group; R' is H, alkyl, aryl or acyl; and X is O or S; possess neuropsychotropic activity. The compounds wherein X is O can be produced by saponifying and decarboxylating a corresponding 2-pyrrolidone-3-carboxylic acid alkyl ester or cyclizing a corresponding 3-phenyl-4-amino-butyric acid or alkyl ester thereof. The pyrrolidones can be converted to the corresponding thiopyrrolidones by reaction with phosphorous pentasulfide in the presence of base.

4-(Polyalkoxyphenyl)-2-pyrrolidones of the formula ##STR1## wherein R.sub.1 and R.sub.2 each are hydrocarbon of up to 18 carbon atoms or alkyl of 1-5 carbon atoms substituted by halogen, OH, COOH, alkoxy, alkoxycarbonyl, carboxamido or amino or collectively are alkylene of 1-3 carbon atoms, R.sub.3 is H or OCH.sub.3, R.sub.4 is H, alkyl, aryl or acyl and X is O or S possess neuropsychotropic activity. The compounds wherein X is O are produced by saponifying and decarboxylating a corresponding 2-pyrrolidone-3-carboxylic acid alkyl ester or cyclizing a corresponding 3-phenyl-4-aminobutyric acid or alkyl ester thereof. The pyrrolidones are converted to corresponding thiopyrrolidones in a conventional manner, e.g., by reaction with phosphorous pentasulfide in the presence of base.
