متن کاملOne-Pot Synthesis of Phenytoin Analogs in Solvent free Conditions Via the Use of Pestle/ Mortar
phenytoine derivatives were synthesized , via the pinacol condensation with the reaction of 1,3- diphenyl- propane- 1,3- dione (benzyl) analogs with urea or thiourea in presence of slica gel and solid KOH as Solid phase catalyst in the mortar / pestle at room temperatures. The reaction was completed at short reaction times (approximately 15min) and pure products were obtained with high yiel...
