    摘要: 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 andY' represents a group of the formula --COOZ or --CH.sub.2 M, in whichZ is lower alkyl andM is hydroxyl, halogen, cyano or a group of the formula --O--SO.sub.2 R.sup.2, in whichR.sup.2 is lower alkyl or aryl,with the proviso that if R' is phenyl, Y' cannot stand for the group --COOC.sub.2 H.sub.5.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.
