Abstract The kinetics of thermolysis of sucrose in solution in anhydrous dimethyl sulphoxide have been studied. The reaction appears to be facilitated by intramolecular hydrogen-bonding and is inhibited by intermolecular hydrogen-bonding to water or alcohols. The thermolysis yields α- d -glucopyranose (which then anomerises) and the fructofuranosyl carbonium ion which can react with benzyl alcohol

The invention belongs to the fields of pharmaceutical industry, and particularly to an improved stereoselective synthesis of intermediate compounds for the preparation of gliflozins, for example canagliflozin or structurally similar gliflozins. Gliflozins, such as canagliflozin, dapagliflozin, empagliflozin, or ipragliflozin, inhibit the sodium-dependent glucose cotransporter 2 (SGLT2) in the kidney and as such are useful in the treatment of type-2 diabetes.
