摘要
目的:研究头孢唑肟丙匹酯类似物的合成,寻找新的头孢唑肟前药。方法:以2-(2-氨基噻唑-4-基)-2-(Z)-甲氧亚氨基乙酸为原料,通过硫酯化、氨解、酯化、酰胺化反应合成目标化合物。结果与结论:合成了10个目标化合物,所有化合物均未见文献报道,其结构经IR,ESI-MS,1H NMR和元素分析确证。
Aim:To study the synthesis of ceftizoxime alapivoxil analogues and to search for new-type prodrug of ceftizoxime. Methods: Target compounds were synthesized from 2-(2-aminothiazol-4-yl)-2-( Z )-methoxyiminoacetic acid via thioesterification, aminolysis, esterification and amidation. Results and Conclusion: Ten new compounds (V1-10) were synthesized,and their structures were identified by IR,ESI-MS, ^1H NMR and elemental analysis.
