proposed new family of antibacterial agents targeted to the penicillin receptor. The glycine and alanine members of the family have been synthesized, as racemates, in seven steps from the four-carbon synthon diketene and the tert-butyl esters of N-hydroxyglycine and N-hydroxyalanine. Numerous alternatives to diketene have also been examined, but these lead mainly to five-membered cyclic hydroxamates
标题化合物是氨基酸,其氮原子被包含在带有 C5-羟基的六元环状异羟肟酸酯中。它们属于一个提议的针对青霉素受体的新型抗菌剂家族。该家族的甘氨酸和丙氨酸成员作为外消旋物,从四碳合成子双烯酮和 N-羟基甘氨酸和 N-羟基丙氨酸的叔丁酯分七个步骤合成。还研究了许多双烯酮的替代品,但这些主要导致五元环异羟肟酸酯。导致此综合程序的理论考虑进行了一些详细的讨论。它们包括分析天然和非天然青霉素替代物的结构,分析青霉素药效团,青霉素阻断细菌细胞壁合成的化学反应。甘氨酸衍生物相对于藤黄微球菌表现出微弱但真实的活性。丙氨酸衍生物,更接近于...
