以6-氯-2-氯甲基-3-喹啉甲酸乙酯(1)为底物,在无水碳酸钾作为缚酸剂、乙腈作为溶剂、聚乙二醇-400作为相转移催化剂的条件下分别与水杨醛(2a~2i)、邻羟基苯乙酮(2j~2o)及2-羟基-1-萘醛(2p)经“三步一锅法”在超声辅助下回流反应,成功的合成了2-(2-苯(萘)并呋喃基)-6-氯-3-喹啉甲酸衍生物(3a~3p).所合成化合物的结构均通过红外光谱、核磁共振氢谱、核磁共振碳谱和高分辨质谱得以证实.

A facile synthesis of 2-(benzo(naphtho)furan-2-yl)-6-chloroquinoline-3-carboxylic acid derivatives (3a~p) has been described, involving ultrasound-assisted three-step one-pot reaction of ethyl 6-chloro-2-(chloromethyl)quinoline-3-carboxylate (1) with corresponding salicylaldehydes (2a~2i), 1-(2-hydroxyphenyl)ethanones (2j~2o) or 2-hydroxy-1-naphthaldehyde (2p) in the presence of K2CO3 as acid-binding agent and PEG-400 as phase transfer catalyst in refluxing MeCN. The synthesized compounds were new, and their structures had been determined by IR, 1H NMR, 13C NMR and HRMS.

Key words: ethyl 6-chloro-2-(chloromethyl)quinoline-3-carboxylate, benzo(naphtho)furan, PEG-400, ultrasound-assisted, three-step one-pot
