KF-Al_2O_3催化下3,4-二氢-2H-吡喃[3,2-h]喹啉衍生物的合成

Synthesis of 3,4-Dihydro-2H-pyrano[3,2-h]quinoline Derivatives Catalyzed by KF-Al_2O_3

芳醛、8 羟基喹啉与丙二腈或氰乙酸乙酯在KF Al2 O3催化下反应生成一系列新的 3,4 二氢 2H 吡喃 [3,2 h]喹啉衍生物 。

A series of new 3,4 dihydro 2 H pyrano[3,2 h ]quinoline derivatives were synthesized by reaction of arylaldehyde, malononitrile or ethyl cyanoacetate with 8 hydroxyquinoline catalyzed by KF Al 2O 3 and the structure was confirmed by X ray analysis.
