在1,4-二氮杂二环[2.2.2]辛烷(DABCO)促进下,以水为反应介质,通过3-溴乙酰基4-羟基-1-甲基-2-喹啉酮与芳香醛的亲核取代、分子内环化及消除的串联反应,合成了9个新型的呋喃并[3,2-c]喹啉酮类化合物,其结构经^1HNMR,^13CNMR,IR,MS(ESI)和元素分析表征。
A simple and efficient method for the synthesis of novel furo [ 3,2-c ] quinolinone derivatives was developed by a domino nucleophilic/cyclization/elimination reaction in H2 0 of 3-bromoacetyl-4- hydroxy-l-methylquinolin-2-one with aryl aldehydes, in the presence of 1,4-diazabicyclo [ 2.2.21 oc- tane(DABCO). The structures were characterized by 1H NMR, 13 C NMR, IR, MS(ESI) and elemen- tal analysis.
