| 摘 要： | Microwave-assisted synthesis of new 2-arylpyrimido4′,5′：4,5]thiazolo3,2-α]benzimidazol-4（3H）-ones from 3-aminothia- zolo3,2-α]benzimidazol-2-earboxamide and aroyl halides in solvent-free condition is described. In comparison with classical conditions the reactions are faster and the yields are higher under microwave irradiation.

| Abstract: | Microwave-assisted synthesis of new 2-arylpyrimido4′,5′:4,5]thiazolo3,2-a]benzimidazol-4(3H)-ones from 3-aminothiazolo3,2-a]benzimidazol-2-carboxamide and aroyl halides in solvent-free condition is described. In comparison with classical conditions the reactions are faster and the yields are higher under microwave irradiation. |
