Claims
- 1. A compound of the general formula: ##STR5## wherein X is an optically determinable residue that is .alpha.-glycosidically bound to the terminal oxygen atom;
- n is 1 or 2;
- and when n is 1,
- R.sub.1 is selected from the group consisting of
- (a) a straight-chained or branched alkyl or alkoyl group containing up to 6 carbon atoms,
- (b) a cycloalkyl or cycloalkoyl group containing 3 to 6 carbon atoms,
- (c) a hydrophilically substituted cycloalkyl or cycloalkoyl group containing 3-6 carbon atoms, or
- (d) a benzyl, benzoyl or phenyl group and
- R.sub.2 is a hydrogen atom or R.sub.1 and R.sub.2 together form a methylene bridge, the hydrogen atoms of which, independently of one another, can each be replaced by an alkyl group containing up to 5 carbon atoms or a phenyl group and,
- when n is 2,
- R.sub.1 is selected from the group consisting of
- (a) a straight-chained or branched alkyl group containing up to 6 atoms,
- (b) a cycloalkyl radical containing 3 to 6 carbon atoms,
- (c) a hydrophilically substituted cycloalkyl group containing 3-6 carbon atoms, or
- (d) a phenyl radical or a benzyl radical,
- and R.sub.2 is a hydrogen atom.
- 2. A compound of the general formula: ##STR6## wherein X is an optically-determinable residue that is .alpha.-glycosidically bound to the terminal oxygen atom and is selected from the group consisting of resorufin, chlorophenol red, an azo dye, an azamethine dye, a styryl dye, a nitrophenol mono- or di-substituted in the ortho position and an umbelliferone 1,
- R.sub.1 is selected from the group consisting of
- (a) a straight-chained or branched alkyl or alkoxy group containing up to 6 carbon atoms,
- (b) a cycloalkyl or cycloalkoyl radical containing 3 to 6 carbon atoms, or
- (c) a hydrophilically substituted benzoyl or phenyl radical, and
- R.sub.2 is a hydrogen atom or R.sub.1 and R.sub.2 together form a methylene bridge, the hydrogen atoms of which, independently of one another, can each be replaced by an alkyl group containing up to 5 carbon atoms or a phenyl group.
- 3. A compound of claim 1, wherein X is 2-chloro-4-nitrophenyl.
- 4. A compound of claim 2, wherein X is 2-chloro-4-nitrophenyl.
- 5. A compound of claim 2, wherein X is 2-fluoro-4-nitrophenyl.
- 6. A compound of claim 2, wherein X is 2-bromo-4-nitrophenyl.
- 7. A compound of claim 4, wherein R1 is isobutyryl.
- 8. A compound of claim 4, wherein R1 is acetyl.
