biological activities of the γ-lactam analogues (-25), (-25) and (26) of carbapenicillanic acids are described. The strategy employed for the synthesis of effected construction of a γ-lactam onto a preformed azetidine, followed by direct amination of the lactam enolate (20) with diphenylphosphinoyl-hydroxylamine. X-ray crystallographic studies demonstrated that the analogues bore a strong morphological
描述了碳青霉烯酸的γ-内酰胺类似物(-25),(- 25)和(26)的合成和生物活性。用于将有效的γ-内酰胺结构合成到预先形成的氮杂环丁烷上,然后用二苯基膦酰基-羟胺直接胺化内酰胺烯酸酯(20)的策略。X射线晶体学研究表明,类似物与碳青霉烯酸具有很强的形态相似性。然而,它们被证明没有抗菌和β-内酰胺酶抑制活性。1个
