Oxazolone derivative 3a was utilized as a versatile precursor for the construction of new heterocyclic scaffolds containing imidazole, oxazine, triazine, and triazole rings (compounds 20, 21, 23, and 24, respectively). Furthermore, 4‐aminohippuric acid (2b) was used in the synthesis of various new oxazolone derivatives (13–19) by utilizing of its amino group in several transformations followed by heterocyclization
恶唑酮衍生物3a中被(化合物用作含咪唑,恶嗪,三嗪,和三唑环新杂环的支架的结构的多功能前体20,21,23,和24分别)。此外,4-氨基马尿酸(图2b)中的溶液在各种新的恶唑酮衍生物(的合成中使用13 - 19)通过在几个变换其氨基的利用随后用醛这些化合物的heterocyclization 1通过经典的Erlenmeyer缩合方法得到目标恶唑酮。上这些化合物作为抗氧化剂和抗菌剂的评价,化合物20和24表现出良好的抗氧化活性,而化合物20,23和24表现出对良好的抗菌活性的大肠杆菌和金黄色葡萄球菌。
