设计以简单易得合成子β-烯胺酮1为原料,以氰基乙酸2为酰基化试剂,得到烯胺酮的α-C区域选择性氰基乙酰化产物3. 进而从化合物3出发,以乙腈为溶剂,哌啶为催化剂,在40 ℃下,通过分子内环合反应,简洁、高效合成了一类结构新颖的喹啉酮类杂环化合物4a~4t,产率82~95%. 该方法具有操作简便、原子经济、原料易得、后处理简单等优点.

A concise and efficient protocol for the synthesis of novel quinolinone derivatives 4 has been established from a intramolecular cyclization of cyanoacetylenaminones 3, which were synthesized by the regio-selective cyanoacylation reaction of β-enaminones 1 with cyanoacetic acid 2. The reaction was performed in acetonitrile media at 40 ℃, and piperidine as catalyst. As a result, a novel series of quinolinones 4a~4t were obtained with the yields of 82%~95%. The reaction is particularly attractive due to the following advantages of operational simplicity, atom economy, simple starting materials, and easy purification.

Key words: β-enaminones, regionselectivity acylation, intramolecular cyclization, quinolinones
