Azetidinone acetic acid derivatives and process for the preparation thereof

The invention relates to compounds of the general formula (X) STR1 wherein R is as a removable protecting substituent of the amido group a phenyl group or a benzyl group substituted by one or more alkoxy group(s) having 1-4 carbon atoms and R1 stands for a hydrogen atom or an alkyl group having 1-4 carbon atoms and a process for the preparation thereof. The compounds of the general formula (X) can be prepared from the starting materials of the general formula (V), wherein R and R1 are as stated above and Z is an alkyl group having 1-4 carbon atoms. The compounds of the general formula (X) are useful pharmaceutical intermediates which can be used in the preparation of known antibiotics (e.g. Thienamycin and PS-5).

Heterocyclic compounds containing an alkoxycarbonyl and a substituted methyl group

The invention relates to new heterocyclic compound containing an alkoxycarbonyl and a substituted methyl group a process for the preparation of these and analogeous compound and pharmaceutical compositions containing them. More particularly, the invention concerns compounds of the general formula (IVa) STR1 wherein R' is hydrogen, 2-ethoxycarbonylethyl, aryl or a group suitable for a temporary protection of amides and Y' represents a group of the formula --COOZ or --CH2 M, in which Z is lower alkyl and M is hydroxyl, halogen, cyano or a group of the formula --O--SO2 R2, in which R2 is lower alkyl or aryl, with the proviso that if R' is phenyl, Y' cannot stand for the group --COOC2 H5. The invention further relates to a process for the preparation of compounds of the general formula (IV) STR2 in which R and Y are identical with R' and Y', respectively, except the proviso. According to a further aspect of the invention there are provided pharmaceutical compositions, first of all with antihypoxic activity, comprising compounds of the general formula (IVa) as active ingredient.
