The synthesis of some substituted 7-hydroxy-5H-1,3,4-oxadiazolo [3,2-a]pyrimidin-5-ones, a class of bicyclics with unexplored pharmacotoxicological properties, is described. Reacting the 2-phenyl derivative with bis(2,4,5-trichlorophenyl)benzylmalonate afforded a linear pyrano-oxadiazolopyrimidinedione. The assigned structures were verified by IR, 1H-NMR, and mass spectral studies. Six compounds of

A series of new 2-substituted-5-(2-benzyloxyphenyl)-1,3,4-oxadiazoles have been synthesized and evaluated as anticonvulsant agents. Compound 4b shows considerable anticonvulsant activity both in PTZ and MES models. It seems this effect is mediated through benzodiazepine receptors mechanism. (c) 2005 Elsevier Ltd.
