or complete deprotection of the phosphonate ester have been realised by either acidic hydrolysis or by treatment with trimethylsilyl bromide. Evaluation against penicillin-binding proteins has shown that our compounds are modest inhibitors of class A beta-lactamases, but have an interesting activity against R39 (D,D-peptidase/carboxypeptidase).

氨基膦酸和氨基双(膦酸)已通过席夫碱与溴乙酸甲酯或丙烯酸乙酯的烷基化反应制备。其他途径,如改良的 Pudovik 反应和 Kabachnik-Fields 反应,已被考虑用于合成氨基柠檬酸盐的 a-膦酸生物电子异构体。膦酸酯的部分或完全脱保护是通过酸性水解或用三甲基甲硅烷基溴处理实现的。对青霉素结合蛋白的评估表明,我们的化合物是 A 类 β-内酰胺酶的适度抑制剂,但对 R39(D,D-肽酶/羧肽酶)具有有趣的活性。((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
