3-c]quinoline derivatives is reported. The easily accessible 2,3-dihydro-lH-quinolin-4-ones were used as the starting materials and were functionalized with three different acylating agents affording their respective constrained core substrates. The latter by condensation with phenyl(or 4-methoxyphenyl)hydrazines and subsequent debenzylation or demethylation provided the desired pyrazole derivatives. Some
报道了三种新型吡唑并[4,3-c]喹啉衍生物的制备。容易获得的 2,3-二氢-1H-喹啉-4-酮用作起始材料,并用三种不同的酰化剂进行官能化,从而提供它们各自的受限核心底物。后者通过与苯基(或4-甲氧基苯基)肼缩合并随后脱苄基或脱甲基提供所需的吡唑衍生物。关于这些反应的区域选择性和机制,出现了一些有趣的特征。
