Abstract A new series of 2,4,5-trisubstituted oxazole were synthesized with good yields using simple methodology. All the compounds were thoroughly characterized by IR, NMR (1H and 13C) and mass spectrometry and structures of 2-(4-butyloxyphenyl)-4,5-dimethyloxazole (5b) and 4,5-dimethyl-2-(4-(octyloxy)phenyl)oxazole(5e) were unambiguously determined by X-ray crystallography. Evidently, the crystal
摘要 采用简单的方法合成了一系列新的2,4,5-三取代恶唑,收率良好。所有化合物均通过 IR、NMR(1H 和 13C)和质谱以及 2-(4-丁氧基苯基)-4,5-二甲基恶唑 (5b) 和 4,5-二甲基-2-(4-(辛氧基)苯基)恶唑(5e)通过 X 射线晶体学明确确定。显然,这些化合物的晶体结构表现出C-H⋯N和C-H⋯O分子间相互作用。这些化合物的电子结构也通过 DFT 在 B3LYP/6-311G ++ 理论水平进行了研究。
