PROCESS FOR THE REPAIR OF PENEMIC ESTERS WITH ANTIBACTERIAL ACTION AND PHARMACEUTICAL COMPOSITIONS THAT CONTAIN THEM |
| abstract |
There is provided a process for preparing penem esters having antibacterial activity, starting from a compound of formula (II) wherein R1 is H or a hydroxy protecting group and Z is a C1-C10 alkyl or an aryl group which is reacted with a compound of formula (III) to give an azeotidinon which is condensed with a compound of the formula (V): XOC - COO - CH2OCOCH3, and cyclized to obtain the desired penem esters. The present invention also comprises a process for preparing a compound of formula (V) oxydizing a compound of the formula: HO-CH2-COO-CH2OCOCH3. |
