The reaction of methanetricarboxylates 2a,b with indoline as well as 1,2,3,4-tetrahydroquinoline yields tricyclic 4-hydroxy-2(1H)-quinolones with an ester group in position 3 (3, 8a,b). These heterocyclic esters condense with primary aliphatic, aromatic, and heteroaromatic amines to give the corresponding amides 5a-e and 10a-t.
甲烷三羧酸酯2a,b与二氢吲哚以及1,2,3,4-四氢喹啉的反应产生在位置3(3,8a,b)具有酯基的三环4-羟基-2(1 H)-喹诺酮。这些杂环酯与脂族,芳族和杂芳族伯胺缩合,得到相应的酰胺5a-e和10a-t。
