the construction of 2-substituted quinolines and benzo[f]quinolines from aromatic amines, aldehydes, and tertiary amines has been demonstrated. Cheap and readily available tertiary amines acted as the vinyl source. A new pyridine ring was selectively formed via [4 + 2] condensation that was promoted by ammonium salt under neutral conditions and an oxygen atmosphere. This strategy provided a new route
已经证明了一种从芳香胺、醛和叔胺构建 2-取代喹啉和苯并 [ f ] 喹啉的无金属方法。廉价且容易获得的叔胺充当乙烯基来源。在中性条件和氧气气氛下,通过铵盐促进的[4 + 2]缩合选择性地形成新的吡啶环。该策略为制备吡啶环上具有不同取代基的多种喹啉衍生物提供了一条新路线,为进一步修饰提供了可能。

An object of the present invention is to provide a probe for imaging a β-sheet structure protein which can be used for the diagnosis of conformational diseases, particularly disease (tauopathy) having a cardinal symptom such as intracerebral accumulation of tau protein, for example, Alzheimer's disease. Another object of the present invention is to provide a compound which is highly specific to tau and can image tau with satisfactory sensitivity, and also has high brain transition, low or non-recognized bone-seeking properties and low or non-recognized toxicity.
According to the present invention, the above problems are solved by providing a compound of a formula I (wherein A, R
