    • The invention relates to novel oxazinones designed to bind to the penicillin receptor, methods of synthesizing the compounds, and the use of the compounds as antibacterial agents. The compounds have the general formula (I) Preferably the compounds have a carboxyethyl or a substituted carboxymethyl substituent at the 2-position and a hydroxyl group at the 5-position and have a molecular shape suitable for binding to and reacting with the active site of a pencillin-recognizing enzyme. The compounds are synthesized by condensing a carboxyl-protected N-hydroxy amino acid with a 3-hydroxyprotected-4-bromobutanoic acid to form a a doubly protected N-hydroxy N-acylamino acid, which is cyclized with an organic base to yield a: doubly protected 1,2-oxazin-3-one. The protecting groups are then removed to provide an antibacterial agent.
    • 本发明涉及设计用于结合青霉素受体的新型恶嗪酮,合成化合物的方法以及该化合物作为抗菌剂的用途。 化合物具有通式(I)。优选地,化合物在2-位具有羧乙基或取代的羧甲基取代基,在5-位上具有羟基,并具有适于与活性位点结合并与其反应的分子形状 一种青霉素识别酶。 通过将羧基保护的N-羟基氨基酸与3-羟基保护的-4-溴丁酸缩合形成双重保护的N-羟基N-酰基氨基酸合成化合物,其与有机碱环化,得到:双 保护的1,2-恶嗪-3-酮。 然后除去保护基团以提供抗菌剂。
