Imaging agents of formulas (I)-(V) and methods for detecting neurological disorders comprising administering to a patient in need compounds of formulas (I)-(V) capable of binding to tau proteins and β-amyloid peptides are presented herein. The invention also relates to methods of imaging Aβ and tau aggregates comprising introducing a detectable quantity of pharmaceutical formulation comprising a radiolabeled compound of formulas (I)-(V) and detecting the labeled compound associated with amyloid deposits and/or tau proteins in a patient. These methods and compositions enable preclinical diagnosis and monitoring progression of AD and other neurological disorders.

A novel and efficient three-component reaction with two C–N bonds and one C–F bond formation has been reported, which provides a straightforward route to a variety of fluorinated pyrimido[1,2-b]indazole derivatives. This transformation has the advantage of excellent functional group compatibility, including aliphatic and aromatic substituents enaminones. Moreover, metal and additives are not necessary
已经报道了一种具有两个 C-N 键和一个 C-F 键形成的新型高效三组分反应,它为各种氟化嘧啶并[1,2- b ]吲唑衍生物提供了一条直接的途径。这种转变具有优异的官能团相容性的优点,包括脂肪族和芳香族取代基烯胺酮。此外,该反应不需要金属和添加剂,这对含氟杂环化合物的合成和应用具有重要意义。
