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.
这项发明属于制药行业领域,特别是改进的立体选择性合成中间化合物,用于制备格列非嗪,例如坎格列非嗪或结构类似的格列非嗪。格列非嗪,如坎格列非嗪、达格列非嗪、恩帕格列非嗪或依帕格列非嗪,抑制肾脏中的
钠依赖型
葡萄糖协同转运蛋白2(SGLT2),因此在治疗2型糖尿病中很有用。
