| titleOfInvention | Process for producing 7-amino-7-alkoxycephalosporins |
| abstract | A 7-(5-amino-5-carboxyvaleramido)-7-methoxycephalosporin with amino and acid groups protected is reacted with PCl 5 or other agent capable of forming an imino halide; the resulting imino halide is thereafter reacted under essentially non-aqueous conditions with a primary loweralkanol of C 1 -C 4 or with methan-d 3 -ol, yielding nucleus bearing a 7-alkoxy group derived from the primary loweralkanol or methan-d 3 -ol. In situ acylation of the nucleus affords 7-acylamido-7-alkoxycephalosporins in good yield; these products can be deesterified to yield the corresponding acids, which exhibit antibacterial activity. |
