Process for preparing penem esters |
| abstract |
THERE IS PROVIDED A PROCESS FOR PREPARING PENEM ESTERS HAVING ANTIBACTERIAL ACTIVITY, STARTING FROM A COMPOUND OF THE FORMULA (II): (FORMULA II) WHEREIN R2 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 THE FORMULA (III) (FORMULA III) TO GIVE AN AZETIDINONE WHICH IS CONDENSED WITH A COMPOUND OF THE FORMULA (V): XOC - COO - C2- OCOCH3 AND CYCLIZED TO OBTAIN THE DESIRED PENEM ESTERS. THE PRESENT INVENTION ALSO COMPRISES A PROCESS FOR PREPARING A COMPOUND OF THE FORMULA (V) OXYDIZING A COMPOUND OF THE FORMULA : HO-CH2-C00-CH2OCOCH3 |
