چکیده
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. The crystal structure is additionally stabilized by weak C-H⋯O inter-actions.

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 کاملSynthesis of glycosylthiols and reactivity studies.
The acid-catalyzed reaction of 1,2-anhydro-3,4,6-tri-O-benzyl-α-d-glucopyranose (7) as glycosyl donor with bis-trimethylsilyl sulfide as acceptor affords the α-thiol. Hence, this sterically hindered S-nucleophile as acceptor should provide with O-glycosyl trichloroacetimidates as glycosyl donors that have nonparticipating groups at C-2, glycosylthiols with the thiol group in axial position. Thi...
متن کاملA facile regio- and stereoselective synthesis of mannose octasaccharide of the N-glycan in human CD2 and mannose hexasaccharide antigenic factor 13b.
A highly concise and effective synthesis of the mannose octasaccharide of the N-linked glycan in the adhesion domain of human CD2 was achieved via TMSOTf-promoted selective 6-glycosylation of a trisaccharide 4,6-diol acceptor with a pentasaccharide donor, followed by deprotection. The pentasaccharide was constructed by selective 3,6-diglycosylation of 1,2-O-ethylidene-beta-D-mannopyranose with ...

In the title compound, C30H33BrO6, the pyran-ose ring adopts a chair conformation. Two of the O-benzyl phenyl rings lie almost perpendicular to C/C/C/O plane formed by the ring atoms not attached to these O-benzyl phenyl rings, and form dihedral angles of 85.1 (2) and 64.6 (2)°, while the third O-benzyl phenyl ring is twisted so that it makes a dihedral angle 34.9 (2)° to this C/C/C/O plane. Th...
