In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of rare sugar isomers through site-selective epimerization, published in 2020-02-29, which mentions a compound: 1824-94-8, Name is (2R,3R,4S,5R,6R)-2-(Hydroxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol, Molecular C7H14O6, Category: chiral-phosphine-ligands.
Here we report the preparation of rare sugar isomers directly from biomass carbohydrates through site-selective epimerization reactions. Mechanistic studies establish that these reactions proceed under kinetic control, through sequential steps of hydrogen-atom abstraction and hydrogen-atom donation mediated by two distinct catalysts. This synthetic strategy provides concise and potentially extensive access to this valuable class of natural compounds
As far as I know, this compound(1824-94-8)Category: chiral-phosphine-ligands can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
