【摘要】：以7-ACA為起始原料,在環(huán)己烷中用六甲基二硅氨烷(HMDS)和三甲基碘硅烷(TMSI)將7-ACA中的氨基和羧基硅烷化,然后與N-甲基吡咯(NMP)和TMSI的反應(yīng)產(chǎn)物混合,生成(6R,7R)-7-氨基-3-[(1-甲基-1-吡咯烷摀鹽)甲基]頭孢-3-烯-4-羧酸氫碘酸鹽(中間體Ⅱ),再與活性酯反應(yīng)得到鹽酸頭孢吡肟。
[Abstract]:Using 7-ACA as the starting material, the amino and carboxyl silanes in 7-ACA were synthesized by using hexamethyldisilyl (HMDS) and trimethyl iodiosilane (Ti) in cyclohexane, and then mixed with the reaction products of N-methylpyrrole (NMP) and TMSI. Cefpyridoxime hydrochloride was obtained by the reaction of ~ (6) R ~ + -7R ~ + -7- amino -3- [1-methyl-1-pyrrolidine] methyl] cef-3-ene-4-carboxylic acid hydroiodate (intermediate 鈪，
