摘要
以6-氯-2-氯甲基-3-喹啉甲酸乙酯(1)为底物,在溶剂无水乙醇中与胺及胺的衍生物2a-p反应,以较好的收率(64.8-77.7%)得到7-氯-2,3-二氢-1H-吡咯并[3,4-b]喹啉-1-酮衍生物,其中与芳胺反应生成N-芳基取代的化合物3a-i,与氨水、甲胺、乙胺和苄胺反应生成N-烷基取代的化合物3j-m,与乙二胺、丙二胺及丁二胺反应生成具有对称结构的化合物3n-p.该反应具有操作简便、条件温和等特点.所有化合物均为新化合物,其结构经IR、1H NMR、13C NMR、MS和HRMS得以证实.
In the present investigation,ethyl 6-chloro-2-( chloromethyl) quinoline-3-carboxylate( 1) as starting compound was subjected to the reaction with different amines such as aromatic amines( 2a-i),aliphatic amine( 2j-m),and diamines( 2n-p) to give the corresponding N-aryl-substituted( 3a-i),N-alkyl-substituted( 3j-m),and symmetrical N,N'-alkyl-bridged( 3n-p) 7-chloropyrrolo[3,4-b]quinolin-1-one derivatives,respectively,with good yields ranging 64. 8-77. 7%. The procedure had the advantages of simple operation,mild reaction. All of compounds were new and their structures were determined by IR,1H NMR,13 C NMR,MS and HRMS.
