| titleOfInvention | Process for preparing penem derivatives |
| abstract | A process for the preparation of the compounds of the formula (II): <IMAGE> and salts and cleavable esters thereof wherein R1 is a hydrocarbon group of up to 12 carbon atoms and which optionally also contain up to 4 heteratoms selected from oxygen, nitrogen, sulphur or chlorine and bromine which process comprises the reaction of a cleavable ester of a compound of the formula (III): <IMAGE> with one equivalent of a strong base of low nucleophilicity and thereafter with a compound of the formula (IV) or (V): <IMAGE> wherein R<1>1 is a group R1 in which any amino substituent is protected and R<2> is an alkyl group of 1-4 carbon atoms optionally substituted by a phenyl group or is a phenyl group optionally substituted by an alkyl group off carbon atoms and thereafter if desired cleaving the ester moiety to yield the acid of the formula (II) or a salt thereof and removing the protecting group from any protected amino group present in R<1>1; is described. |
