A practical process for the preparation of remogliflozin etabonate, a prodrug of the selective low-affinity Na+-dependent glucose co-transporter (SGLT2) inhibitor, remogliflozin, is described. We established a chemoselective synthetic route to 1,2-dihydro-4-[(4-isopropoxyphenyl)methyl]-1-isopropyl-5-methyl-3H-pyrazol-3-one and an efficient O-glycosylation of this compound with 2,3,4,6-tetra-O-pivaloyl-α-D-glucopyranosyl bromide. This synthetic process provided remogliflozin etabonate in a 39% overall yield from commercially available 4-isopropoxybenzaldehyde.

Inhibition of the sodium-glucose co-transporters (SGLT1 and SGLT2) is a validated strategy to address the increasing prevalence of type II diabetes mellitus. However, achieving selective inhibition of human SGLT1 or SGLT2 remains challenging. Orally available small molecule drugs based on the d-glucose core of the natural product Gliflozin have proven to be clinically effective in this regard, effectively impeding glucose reabsorption. Herein, we disclose the influence of molecular editing with fluorine at the C2 position of the pyranose ring of Phlorizin analogues Remogliflozin Etabonate and Dapagliflozin (Farxiga) to concurrently direct β-selective glycosylation, as is required for biological efficacy, and enhance aspects of the physicochemical profile. Given the abundance of glycosylated pharmaceuticals in diabetes therapy that contain a β-configured d-glucose nucleus, it is envisaged that this strategy may prove to be expansive.
O-glycosylation of 4-(substituted benzyl)-1,2-dihydro-3H-pyrazol-3-one derivatives with 2,3,4,6-tetra-O-acyl-α-D-glucopyranosyl bromide via N1-acetylation of the pyrazole ring
