| 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-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.
