This present invention relates to a glucopyranosyl derivative as sodium dependent glucose cotransporters (SGLTs) inhibitor, preparation processes thereof, and pharmaceutical uses thereof, pharmaceutical compositions containing the compound and their uses for treating diabetes and diabetes-related diseases. The process of the invention has simple operation, high optical purity of product, high yield and convenient work-up, easy purification, and is suitable for industrial production.
Efficient and selective: Two lipophilic catalysts were used for Baeyer–Villiger (BV) oxidations to give lactones in high yields (see scheme). Cascadereactions involving this BV oxidation were used to selectively obtain either unsaturated carboxylic acids or hydroxylactones in high yields from β‐silyl cyclohexanones.
