钯(0)催化的2-卤代喹喔啉与功能取代的偶联炔烃,向由此产生的2-炔基喹喔啉中加入一摩尔当量的溴,然后使生成的二溴化物与 三硫代碳酸二钠产生了2-羟甲基-和2-(二乙氧基甲基)噻吩并[2,3- b ]喹喔啉。将溴添加到一些6-取代的2-(3,3-二乙氧基丙炔-1-基)喹喔啉中,得到吡咯并[1,2- a ]喹喔啉。用以下试剂处理3-(1,2-二溴代烯基)喹啉,3-(1,2-二溴代烯基)吡嗪和5-(1,2-二溴代烯基)嘧啶三硫代碳酸二钠 未能诱导噻吩环形成。

A novel, microwave-assisted. palladium-catalyzed Sonogashira-type coupling of terminal alkynes with a variety of heteroaryl thiomethylethers is reported. The developed protocol allows for further utility and diversification of a number of chemically and biologically interesting scaffolds, (C) 2008 Elsevier Ltd. All rights reserved.
