    摘要: The present invention provides compounds of the general formula ##STR1## wherein R.sub.1 is a hydrogen atom, a methyl, ethyl, propyl, isopropyl, butyl, tert. butyl or 1-alkoxyalkyl radical or an optionally hydrophilically substituted cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, phenyl, tetrahydropyranyl, piperidinyl, N-methyl substituted piperidinyl or N-ethyl substituted piperidinyl, pyridinyl, thiophenyl or 1,1-dioxo-tetra- hydrothiopyranyl radical or an amino group which is optionally substituted by the same or different substituents selected from methyl, ethyl, propyl and isopropyl radicals. R.sub.2 is an oligoglucoside residue with 2, 3 or 4 glucose units and X is a hydrogen atom or an optically determinable residue. The present invention also provides processes for the preparation of compounds (I) and reagents for the determination of .alpha.-amylase containing them. Furthermore, the present invention provides a process for the determination of .alpha.-amylase using a compound of general formula (I).
