7-(or 6-) Substituted-7-(or 6-)acylimino cephalosporin (or penicillin) compounds |
摘要 |
A process is provided which yields derivatives of cephalosporins and penicillins. The process starts with 7-aminodecephalosporanic acid or 6-APA and reacts with a carbonyl containing compound to form a Schiff's base (imino) adduct. This latter compound is then treated with a defined reactant yielding a novel Schiff's base adduct having a side chain on the carbon adjacent to the imino-nitrogen. The amino moiety can be regenerated and further reacted to form end compounds which are active against both gram-positive and gram-negative bacteria.
