Preparation, single-crystal X-ray diffraction and high-resolution NMR spectroscopic analyses of N-[(1,4-anhydro-5-deoxy-2,3-O-isopropylidene-d,l-ribitol)-5-yl]trimethylammonium iodide

The synthesis and isolation of 1,4-anhydro-5-deoxy-5-iodo-2,3-O-isopropylidene-d,l-ribitol and N-[(1,4-anhydro-5-deoxy-2,3-O-isopropylidene-d,l-ribitol)-5-yl]trimethylammonium iodide are described. The products were examined by 1H, 13C NMR spectroscopy, and N-[(1,4-anhydro-5-deoxy-2,3-O-isopropylidene-d,l-ribitol)-5-yl]trimethylammonium iodide was additionally analyzed by X-ray crystallography.
