2-[(2R,3S,4S,5S)-3,4-Benz­yloxy-2,5-bis(trityloxymethyl)tetra­hydro­furan-2-yl­oxy]-3,4,5-tribenz­yloxy-6-(trityloxymeth­yl)tetra­hydro­pyran–methanol–2-butanone (1/1/0.75)

In the sugar mol­ecule of the title compound, C₁₀₄H₉₄O₁₁·CH₄O·0.75C₄H₈O, the pyran­ose ring adopts the expected chair conformation. Weak intra- and inter­molecular C—H⋯O hydrogen bonds, in part, control the mol­ecular conformation and stabilize the crystal structure.
