One-Pot Synthesis of Phenytoin Analogs in soilution Conditions

Abstract

phenytoine derivatives were synthesized , via the pinacol condensation with the<br />reaction of 1,3- diphenyl- propane- 1,3- dione (benzyl) analogs with urea or thiourea<br />in presence of slica gel and solid KOH as Solid phase catalyst in the mortar / pestle at<br />room temperatures. The reaction was completed at short reaction times (approximately<br />15min) and pure products were obtained with high yields (81-94%).
