Oligoglucosides of the general formula …<IMAGE>… in which R1 is a hydrogen atom, a straight-chain or branched alkyl group with 1 to 4 carbon atoms, a 1-alkoxyalkyl or an optionally hydrophilically substituted cycloalkyl group with 3 to 6 carbon atoms, a phenyl, tetrahydropyranyl, piperidinyl, optionally N-methyl- or ethyl-substituted, pyridinyl, thiophenyl, 1,1-dioxotetrahydrothiopyranyl group, or an amino group which is optionally substituted identically or differently by a methyl, ethyl, propyl or isopropyl group, R2 is an oligoglucoside residue with 2, 3 or 4 glucose units and X is a hydrogen atom or a radical which can be determined optically, and processes for the preparation thereof. The compounds are suitable as substrates for the determination of alpha -amylase activity. |
