Synthesis and anticonvulsant properties of some novel quinazolinone thiazolidine and 4-thiazolidone derivatives

A series of quinazolinone thiazolidine and 4-thiazolidone derivatives were prepared. The structure of the isolated products have been confirmed by elemental analyses, spectroscopic data and ambiguous synthesis in certain cases. Some of these compounds wer

Synthesis and CNS Activity of 4-Arylideneamino-N,N-diphenylbenzamides, 1--3-(p-substituted phenyl)thioureas and 6-Substituted 3-2-oxo/thio-benzoxazoles

4-Arylideneamino-N,N-diphenylbenzamides (IIIa-h), 1--3-(p-substituted phenyl)thioureas (IVa-d) and 6-substituted 3--2-oxo-/thio-benzoxazoles (Va-d) have been synthesized from 4-amino-N,N-diphenylbenzamide (IIa).Similarly thioureas IVe-h and benzoxazoles Ve-h have been prepared from 2-aminoquinazolin-4(3H)-one (IIb).Compounds III, IV and V are found to be psychotropic and nontoxic.
