Abstract A neat and rapid procedure is reported for the synthesis of a variety of 2‐aryloxymethylene‐6‐arylimidazo[2,1‐b]‐1,3,4‐thiadiazole (3a–3r) by condensation reaction of 2‐amino‐5‐aryloxymethylene‐1,3,4‐thiadiazole (1a–1f) with ω‐bromoacetophenone (2a–2c) in ethanol solvent under microwave irradiation, which yielded a series of novel compounds. The yields are good to excellent. The procedure
摘要 报道了一种通过 2-
氨基- 缩合反应合成各种 2-芳氧基亚甲基-6-芳基
咪唑 [2,1-b]-1,3,4-
噻二唑 (3a-3r) 的简洁快速方法。 5-芳氧基亚甲基-1,3,4-
噻二唑(1a-1f)与ω-
溴苯乙酮(2a-2c)在微波辐射下的
乙醇溶剂中,产生了一系列新化合物。产量从好到极好。该过程简单,不需要添加任何催化剂或脱
水剂。此外,晶体不需要进一步纯化即可得到产品。
