  Application of DMF–methyl sulfate adduct in the regioselective synthesis of 3-acylated indolizines

  摘要：

  A number of 3-acylated indolizines were synthesized in good to excellent yields by a newly established reaction between picolinium salts and the methylsulfate salt of A (R = Me), the adduct formed from DMF-Me2SO4 as the key reagent. The low cost, short reaction time, mild reaction condition, and easy purification of the products make this an attractive new method for the synthesis of indolizine compounds. A variety of functional groups (nitro, cyano, ester, methoxy, and halogens) were well tolerated under the reaction conditions. (c) 2007 Elsevier Ltd. All rights reserved.

  Provided herein are compounds and compositions which comprise the formulae as disclosed herein, wherein the compound is an amyloid binding compound. An amyloid binding compound according to the invention may be administered to a patient in amounts suitable for in vivo imaging of amyloid deposits, and distinguish between neurological tissue with amyloid deposits and normal neurological tissue. Amyloid probes of the invention may be used to detect and quantitate amyloid deposits in diseases including, for example, Down's syndrome, familial Alzheimer's Disease. In another embodiment, the compounds may be used in the treatment or prophylaxis of neurodegenerative disorders. Also provided herein are methods of allowing the compound to distribute into the brain tissue, and imaging the brain tissue, wherein an increase in binding of the compound to the brain tissue compared to a normal control level of binding indicates that the mammal is suffering from or is at risk of developing a neurodegenerative disease.

  本文提供的化合物和组合物包含如下所述的公式，其中该化合物是一种淀粉样蛋白结合化合物。本发明的淀粉样蛋白结合化合物可以以适量的方式用于体内成像淀粉样沉积物，以区分含有淀粉样沉积物的神经组织和正常神经组织。本发明的淀粉样探针可以用于检测和定量测量包括唐氏综合症、家族性阿尔茨海默病在内的疾病中的淀粉样沉积物。在另一实施例中，这些化合物可以用于治疗或预防神经退行性疾病。本文还提供了一种使化合物分布到脑组织中并成像脑组织的方法，其中与正常结合水平相比，化合物与脑组织的结合增加表明哺乳动物正在患有或有发展神经退行性疾病的风险。
