Methyl 2-acetamido-2-deoxy-β-D-glucopyranoside dihydrate and methyl 2-formamido-2-deoxy-β-D-glucopyranoside.
Methyl 2-acetamido-2-deoxy-β-D-glucopyranoside (β-GlcNAcOCH(3)), (I), crystallizes from water as a dihydrate, C(9)H(17)NO(6)·H(2)O, containing two independent molecules [denoted (IA) and (IB)] in the asymmetric unit, whereas the crystal structure of methyl 2-formamido-2-deoxy-β-D-glucopyranoside (β-GlcNFmOCH(3)), (II), C(8)H(15)NO(6), also obtained from water, is devoid of solvent water molecul...
متن کامل1,5-Anhydro-3,6-di-O-benzyl-2-deoxy-1,2-C-dichloromethylene-d-glycero-d-gulo-hexitol
In the title compound, C(21)H(22)Cl(2)O(4), the pyranosyl ring adopts a twist-boat conformation with the O-benzyl groups in equatorial positions. In the crystal, O-H⋯O hydrogen bonding results in infinite chains of mol-ecules along [100]. The structure is further consolidated by weak C-H⋯O, C-H⋯Cl and C-H⋯π inter-actions. The absolute structure was determined.
متن کاملFacile synthesis of nitrophenyl 2-acetamido-2-deoxy-α-D-mannopyranosides from ManNAc-oxazoline
The synthetic procedures for a large-scale preparation of o- and p-nitrophenyl 2-acetamido-2-deoxy-α-D-mannopyranoside are described. The synthetic pathway employs the glycosylation of phenol with ManNAc oxazoline, followed by nitration of the aromatic moiety yielding a separable mixture of the o- and p-nitrophenyl derivative in a 2:3 ratio.
متن کامل1,5-Anhydro-2-deoxy-1,2-C-dichloromethylene-3,4,6-tri-O-(4-methoxybenzyl)-d-glycero-d-gulo-hexitol
The pyranosyl ring in the title compound, C(31)H(34)Cl(2)O(7), adopts a twist-boat conformation. The 4-meth-oxy-benzyl groups are located in equatorial positions with the meth-oxy groups nearly coplanar with their respective rings [dihedral angles of 0.2 (3) and 9.4 (2)°]. The aromatic rings adopt orientations enabling them to participate in C-H⋯π inter-actions with neighboring meth-oxy groups....
متن کاملN,N'-Diacetylchitobionic N-alkylamides: synthesis, and interaction with two 2-acetamido-2-deoxy-D-glucose-binding lectins.
Condensation of N,N’-diacetylchitobiono-1,54actone, obtained by oxidation of N,N’-diacetylchitobiose, with n-alkylamines gave NJ’-diacetylchitobionic IValkylamides. The interaction of these glycolipids with wheat-germ agglutinin and Griffonia simplicifolia II lectin is described.
