phenyl)‐pyridin‐2‐yl]‐5‐oxopyrrolidine‐3‐carboxylic acids (3a–t) were designed and synthesized by clubbing pyrrolidinones and pyridines, the two active anticonvulsantpharmacophores. All the synthesized compounds fulfilled the requirements of suggested pharmacophoric model for anticonvulsantactivity. Their in vivo anticonvulsantevaluation was performed by maximal electroshock seizure (MES) and subcutaneous

Trifluoroethanol (TFE) is found to be an efficient and recyclable medium in promoting one-pot, four-component coupling reactions of aldehydes, ketones, malononitrile, and ammonium acetate to afford the corresponding 2-amino-3-cyanopyridine derivatives in high yields. The solvent (TFE) can be readily separated from reaction products and recovered in excellent purity for direct reuse. (C) 2012 Elsevier B.V. All rights reserved.

2-Thioxo-3,5,7-trisubstituted-1-[2',3',5'-tri-O-benzoyl-beta -D-ribofuranosyl]pyrido [2,3-d]pyrimidin-4(1H)-ones have been prepared by the condensation of trimethylsilyl derivative of w2-thioxo-3,5,7-trisubstituted pyrido[2,3-d]pyrimidin-4(IH)-ones with P-D-ribofuranose 1-acetate-2,3,5-tribenzoate in 65%-78% yield. The structure of the synthesized ribofuranosides and their precursors have been established by JR, H-1 NMR and elemental analysis. These derivatives, have been screened for their antimicrobial activity.
