报道了一种简便的一锅法合成8-aryl-7，8-dihydro-[1，3]dioxolo[4，5-g]quinolin-6-(5H)-one和4-芳基-3，4-二氢喹啉-2-(1H)-酮的方法，该反应是在10mol%ZrOCl2.8H(2)O存在下由胺、芳香醛和梅尔德鲁姆酸在超声波作用下进行的。该方法具有催化剂用量少、反应清洁、操作简单、催化剂可回收利用、反应时间短、产率高、无溶剂等优点。本文还提供了补充材料。请访问出版商在线版的合成通信(R)，查看免费补充文件。
A convenient, one-pot, solvent-free reaction of amines, aromatic aldehydes, and Meldrum's acid to form 8-aryl-7,8-dihydro-[1,3]dioxolo[4,5-g]quinolin-6-(5H)-one and 4-aryl-3,4-dihydroquinolin-2-(1H)-one in the presence of 10mol% ZrOCl2.8H(2)O under ultrasonic irradiation is described. This new protocol offers several advantages including low catalyst loading, clean reaction, easy workup, use of recyclable and ecofriendly catalyst, short reaction times, good yields, and solvent-free conditions.
