[ 1 ] - reaction of thiohydantoins and ethylbromopyruvate for Synthesis of imidazo[2,1-b]thiazole 3-carboxylate
Imidazo[2,1-b]thiazoles are obtaind in excellent yields from the addition reaction between thiohydantoin and ethylbromopyruvate. These imidazo[2,1-b]thiazoles in the presence of p-TSA in boiling toluene refluxed for 2.5 hours led to imidazo[2,1-b]thiazole-3-carboxylates in elimination reactions
[ 2 ] - A New synthesis of functionalized imidazo[2,1-b][1,3]thiazines with thiohydantoins, isocyanides and dialkyl acetylenedicarboxylates
The reaction of stoichiometric amounts of dialkyl acetylenedicarboxylates with alkyl isocyanides and 5,5-diaryl thiohydantoins in toluene and catalytic amount of p-TSA afforded imidazo[2,1-b][1,3]thiazines in good overall yields
[ 3 ] - Synthesis of imidazo[2,1-b]thiazole-3-carboxylate through the reaction of thiohydantoins and ethylbromopyruvate
Imidazo[2,1-b]thiazoles are obtaind in excellent yields from the addition reaction between thiohydantoin and ethylbromopyruvate. These imidazo[2,1-b]thiazoles in the presence of p-TSA in boiling toluene refluxed for 2.5 hours led to imidazo[2,1-b]thiazole-3-carboxylates in elimination reactions
