chiral, pyrrolidine-based diamine and triamine derivatives that incorporate the secondary-secondary diamine motif are efficient catalysts for the highly diastereoselective and enantioselectiveMichaeladdition of cyclic ketones to 2-nitrovinyl arenes. The highest selectivities are obtained when these catalysts are used in conjunction with protonic acids. Steric factors in the substrate and the size of
The present invention relates to a glucopyranosyl derivative and a use thereof. In particular, the present invention relates to a glucopyranosyl derivative that is used as an inhibitor of sodium-dependent glucose transporters (SGLTs), particularly being used as an inhibitor of sodium-dependent glucose transporter-1 (SGLT1), and a pharmaceutically acceptable salt or stereoisomer thereof, further relating to a pharmaceutical composition containing the derivative. The present invention further relates to a use of the compound and a pharmaceutical composition thereof in the preparation of a drug for treating diabetes and diabetes-related diseases.
