AZA penem compounds |
| abstract |
Described is a novel process for the preparation of penems and carbapenems useful as antibacterial agents which comprises the reaction of an appropriate 4-substituted-azetidine-2-one with an acid halide in the presence of a tertiary amine and an alkaline earth metal carbonate, followed by reaction of the thereby formed 1-imido-4-substituted-azetidine-2-one with a trialkyl phosphite. n Also described are novel penems useful as antibacterials which are prepared by the described process. |
