5-Deoxy-1,2-O-isopropylidene-5-C-triphenylstannyl-[alpha]-L-xylofuranose

In the title compound, [Sn(C₆H₅)₃(C₈H₁₃O₄)], the L-furanose ring adopts a C4-endo-envelope pucker, with C4 displaced 0.544 (3) Å from the mean plane of the remaining four atoms. The isopropylidene ring adopts a C6-envelope conformation, with C6 displaced -0.439 (3) Å from the mean plane of the remaining four atoms. The Ph₃Sn group has an irregular propeller conformation and the Sn atom has slightly distorted tetrahedral geometry, with Sn-C distances in the range 2.131 (2)-2.150 (2) Å and C-Sn-C angles in the range 106.55 (8)-114.27 (8)°.
