Mutual transitions between α-D-glucose and its monohydrate was written by Ohshima, Kiyoshi. And the article was included in Japanese Journal of Applied Physics in 1974.SDS of cas: 14431-43-7 This article mentions the following:
α-D-glucose was converted to the monohydrate by hydration, and inversely α-D-glucose monohydrate was converted back into the anhydrous form by pyrolysis. In these experiments, the crystal surfaces were observed with an optical microscope, and the crystal structures of both glucoses were studied by x-ray diffraction. Glucose monohydrate exists in the form of rod-like and needle-like granules and in the form of a larger grain shaped like a plate. Powder diffraction lines of both glucoses were analyzed. In the discussion of these exptl. results, the mechanism of mutual transitions is made clear. In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7SDS of cas: 14431-43-7).
(2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7) belongs to tetrahydropyran derivatives. Dihydropyrans and tetrahydropyrans are examples of cyclic ethers widespread in nature. The bismuth chloride-assisted cross-cyclization between homoallylic alcohols and epoxides provided various benzyl tetrahydropyran derivatives. The reaction afforded good yields of desired products and occurred under mild conditions.SDS of cas: 14431-43-7
