Methyl 4-O-benzyl-α-L-rhamno­pyrano­side

In the title compound, C₁₄H₂₀O₅, an inter­mediate in the synthesis of oligosaccharides, the glycosidic [H—C—O—C(H₃)] torsion angle φ_H is 52.3° and the exo-cyclic [H—C—O—C(H₂)] 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 R₃³(12) ring motifs involving three mol­ecules. The chains are linked via C—H...π inter­actions, forming a three-dimensional network.
