Synthesis, Structure and Antioxidant Activity of (Tetra-O-acetyl-β-D-galactopyranosyl)thiosemicarbazones of Substituted Benzaldehydes
Some new substituted benzaldehyde (2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl) thiosemicarbazones were synthesised by reaction of 2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl thiosemicarbazide and different substituted benzaldehydes. The reaction was performed using conventional and microwave-assisted heating methods. The structures of thiosemicarbazones were confirmed by spectroscopic (IR, (1)...
متن کامل2,3,4,6-Tetra-O-acetyl-β-d-galactopyranosyl 2,3,4,6-tetra-O-acetyl-β-d-glucopyranosyl disulfide tetrahydrofuran solvate
The asymmetric unit of title compound, C(28)H(38)O(18)S(2)·C(4)H(8)O, comprises one disulfide-bridged sugar molecule and one solvent molecule. No significant differences in structural parameters are found between the present structure and the previously determined unsolvated form [Brito, López-Rodríguez, Bényei & Szilagyi (2006 ▶). Carbohydr. Res.341, 2967-2972]. The compounds are characterized...
متن کاملSynthesis and antibacterial and antifungal activities of N-(tetra-O-acetyl-β-d-glucopyranosyl)thiosemicarbazones of substituted 4-formylsydnones
BACKGROUND Sydnone is a heterocycle that exhibits remarkable pharmacological activities, including antimicrobial, anti-inflammatory, analgesic, antipyretic and antioxidant activities. Thiosemicarbazones are of compounds that contain the -NHCSNHN=C< linkage group and are considerable interest because they exhibit important chemical properties and potentially beneficial biological activities. Sim...
متن کامل4-(Dimethoxymethyl)phenyl 2,3,4,6-tetra-O-acetyl-β-d-glucopyranoside
The enanti-omerically pure title compound, C(23)H(30)O(12), crystallizes in the chiral space group P2(1)2(1)2(1). The O-acetyl-ated-glucopyran-oside moiety adopts a chair conformation. Numerous C-H⋯O inter-actions as well as a C-H⋯π inter-action are present in the crystal structure.
متن کامل2,3,4,6-Tetra-O-acetyl-2-phthalimido-β-d-glucopyranoside
In the crystal structure of the title compound, C(24)H(27)NO(11), a substituted tetra-acetyl glucopyran-oside derivative, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into ribbons propagated in [010]. The d configuration has been attributed on the basis of the synthesis and the β anomer has been determined from the structure.
