8,9-二氢-2H-吡喃并[5,6-g]喹啉-2-酮衍生物的合成
Synthesis of 8,9-Dihydro-2H-Pyrano-[5,6-g]Quinolin-2-One Derivatives
【摘要】 报道了间氨基酚在PTS·H2 O催化下 ,分别与不同结构的含α 位CH的酮作用后 ,首先进行C环的环合 ,进而与乙酰乙酸乙酯反应 ,区域选择性地得到 8,9 二氢 2H 吡喃并 [5 ,6 g]喹啉 2 酮衍生物的新合成方法
【Abstract】 A concise synthesis of 8,9 dihydro 2 H pyrano [5,6 g]quinolin 2 one derivatives was reported, using 3 amino phenol as starting material. Treatment of 3 amino phenol with ketones bearing α CH at the presence of a catalyst PTS·H 2O affords compound 2a~2d, followed by treatment with ethyl acetoacetate, gives target compound 3a~3d with regioselectivity.
