Methyl 4-O-benzyl-α-l-rhamno­pyrano­side

In the title compound, C(14)H(20)O(5), an inter­mediate in the synthesis of oligosaccharides, the glycosidic [H—C—O—C(H(3))] torsion angle ϕ(H) is 52.3° and the exo-cyclic [H—C—O—C(H(2))] torsion angle θ(H) is −11.7°. The hexa­pyran­ose ring has a chair conformation. In the crystal, mol­ecules are linked by O—H⋯O hydrogen bonds, forming chains propagating along [010]. Enclosed within the chains are R (3) (3)(12) ring motifs involving three mol­ecules. The chains are linked via C—H⋯π inter­actions, forming a three-dimensional network.
