[0110] Synthetic route of Scheme1 intermediate 6a

[0111]

[0112] The first step of preparation of (2S,4R)-N-tert-butoxycarbonyl-4-hydroxypyrrolidine-2-carboxylic acid 2a

[0113] Dissolve 4-OH-L-proline (3.95g, 30.1mmol) in 50mL1,4-dioxane and 50mL1mol·L -1 Add (Boc) to the mixed solution of sodium hydroxide solution at 0°C 2 O (7.85g, 36.0mmol), stirred at low temperature for 0.5h, then raised to room temperature and stirred overnight. Concentrate under reduced pressure and evaporate to near dryness, add 50mL water to dissolve, and use 1mol·L -1 Adjust the pH of the HCl solution to 2-3, extract with ethyl acetate, combine the organic layers, wash the organic layer with saturated brine, dry over anhydrous sodium sulfate, filter, and concentrate under reduced pressure to obtain intermediate 2a, white solid 6.68g, yield About 96.3%. 1 H NMR (D 2 O,300MHz)δ:4.53(br,1H, CH -OH in pyrrolidine),4.42-4.36(m,1H,CHC=O),3.60-3.47(m,2H,CH 2 N in pyrrolidine),2.42-2.35&2.19-...

Abstract

The invention discloses thiomorpholine compounds containing substituted pyrrole alkyl groups, a preparation method and applications thereof. Specifically, the invention relates to compounds represented by the formula (1), stereo isomers, and pharmaceutically-acceptable salts thereof; wherein the R is detailed in the description. The invention further relates to a pharmaceutical composition containing the provided compounds, applications of the compounds in preparation of drugs for treating and / or preventing diseases or symptoms caused by too high activity of DPP-IV or over expression of DPP-IV, and methods using the compounds to treat the diseases mentioned above. The compounds can effectively inhibit the activity of DPP-IV.

Description

technical field [0001] The invention belongs to the technical field of medicine. It relates to thiomorpholine compounds containing substituted pyrrolidinyl represented by general formula (I), pharmaceutically acceptable salts and isomers thereof, preparation of such compounds, pharmaceutical compositions containing them and the Application of compounds in preventing and / or treating diabetes and non-insulin-dependent diabetes, especially in inhibiting DPP-IV. Background technique [0002] Diabetes is a chronic metabolic disease characterized by hyperglycemia. Sustained hyperglycemia can lead to many complications, such as retinal, renal, nervous system and microvascular complications. At present, there are about 246 million people in the world suffering from type 2 diabetes, and the number of patients is expected to reach 380 million within 20 years [Xu Sisheng. Research progress of new antidiabetic drugs. Journal of China Pharmaceutical University. 2011,42(2):97 -106]. D...
