Synthesis of metabolites of dapagliflozin: an SGLT2 inhibitor

Abstract: Dapagliflozin is one of the gliflozin class drugs, useful for the treatment of type-2 diabetes. Dapagliflozin undergoes extensive metabolism and transforms to metabolites in humans. The contribution of pharmacologically active metabolites in drug discovery and development is significant. A streamlined synthetic approach is devised to access three metabolites of dapagliflozin namely, benzylic hydroxy dapagliflozin, oxo dapagliflozin and desethyl dapagliflozin. Two synthetic protocols have been proposed for the synthesis of benzylic hydroxy dapagliflozin and oxo dapagliflozin. An enantioselective deethylation of dapagliflozin is also reported. Graphic abstract: Synthesis of three metabolites of Dapagliflozin namely benzylic hydroxy dapagliflozin, oxo dapagliflozin and desethyl dapagliflozin is reported from commercially accessible raw materials.[Figure not available: see fulltext.]

Synthetic method for empagliflozin related substance IMPD

The invention discloses a synthetic method for empagliflozin related substance IMPD. In a current synthetic method of IMPD, a whole synthetic route is longer and the total yield is lower. The synthetic method provided by the invention comprises the following steps: performing hydroxylation by using (2-chloro-5-iodophenyl)(4-fluorophenyl)methanone as a raw material to obtain (2-chloro-5-iodophenyl)(4-hydroxyphenyl)methanone, performing a reaction by using a carbonyl reducing agent to obtain 4-(5-iodo-2-chlorobenzyl)phenol, protecting phenolic hydroxyl groups by using protecting groups such as TBDMS, performing metallization of aromatic iodide by adopting a relatively stable and safe Grignard reagent i-PrMgCl.LiCl, performing methyl glucoside reduction by using a Lewis acid catalyst, and finally performing quenching to obtain the empagliflozin related substance IMPD. The synthetic method provided by the invention has the advantages of an abundant raw material source, a simple, quick andhigh-efficiency reaction, milder reaction conditions, a higher total yield and low costs.

PROCESS FOR PREPARATION OF DAPAGLIFLOZIN AND INTERMEDIATES THEREOF

Processes for the preparation of dapagliflozin reduce or eliminate impurities in dapagliflozin, preferably individual impurities are not more than 0.15% by HPLC.
