An approach for the synthesis of pyrazolo[4,3-c]quinoline derivatives has been developed by the combination of pyrazole-arylamines and β-keto esters via cleavage of C–C bonds. The strategy shows good tolerance and compatibility with a wide range of functional groups. Moreover, this method features simple conditions, generates a series of alkyl substituted pyrazolo[4,3-c]quinoline, and provides the desired
摘要 吡唑并[4,3-c]喹啉衍生物的合成方法是通过吡唑-芳基胺和β-酮酯通过C-C键的断裂来合成。该策略对多种官能团具有良好的耐受性和相容性。此外,该方法条件简单,可生成一系列烷基取代的吡唑并[4,3-c]喹啉,并以中等至良好的收率提供所需产物。
