چکیده
The title compound, C(21)H(21)BrO(7)·C(2)H(6)O, was synthesized by the Claisen-Schimidt reaction of helicid (systematic name: 4-formyl-phenyl-β-d-allopyran-oside) with 4-bromo-aceto-phenone in ethanol. The pyran ring adopts a chair conformation. In the crystal structure, mol-ecules are linked into a three-dimensional network by inter-molecular O-H⋯O hydrogen bonds.

The asymmetric unit of the title solvate, C(20)H(25)ClO(9)S·0.25CH(3)OH, contains one galactopyranosyl derivative and one-quarter of a methanol solvent mol-ecule. The galactopyran-ose ring is in the usual (4)C(1) conformation, and the anomeric center of the sugar has a β configuration. The value of θ (3.44°) and the range of torsion angles [or 53.1 (5)-63.0 (5)°] reflect a slight distortion of ...
