A novel catalyst (SSA/ethylene glycol) for the efficient synthesis of new benzo[4,5]imidazo[1,2-a]pyrimidine derivatives I (R = H, acetyl; R1 = Me, Ph; R2 = Ph, 3-bromophenyl, thiophen-2-yl, etc.) in high yield and good purity was demonstrated. The reaction was achieved via three-component condensation reactions. SSA/ethylene glycol offers several advantages for the preparation of novel heterocycles I. Among these are simplicity, mild reaction conditions, and little environmental impact. The investigations will spur the exploration of this useful reagent combination in the synthesis of new heterocyclic systems. The experimental part of the paper was very detailed, including the reaction process of 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Related Products of 934-32-7)
1H-Benzo[d]imidazol-2-amine(cas: 934-32-7) can be used in the hydrolysis of a choline carbonate. It was also used in the synthesis of imidazo[1,2-a]benzimidazoles.Related Products of 934-32-7
