title: Crystal structure of 1L-1,2:4,5-di-O-isopropylidene-allo-inositol: a comparison of its conformation in solid and solution states.
abstract: The X-ray crystal structure of 1l-1,2:4,5-di-O-isopropylidene-allo-inositol, is described. The inositol ring deviate slightly from the ideal chair conformation to a flattened chair. A comparison of its conformation in solution with that in solid was made by the use of 1H NMR. This conformational analysis revealed that the title compound adopts similar conformations in solid state and in solution in low polar solvents like benzene and CHCl3 while in high polar solvents such as Me2SO, the solid state conformation is not retained.
