## Abstract The reaction of methanetricarboxylates 2a,b with indoline as well as 1,2,3,4‐tetrahydroquinoline yields tricyclic 4‐hydroxy‐2(1__H__)‐quinolones with an ester group in position 3 (3, 8a,b). These heterocyclic esters condense with primary aliphatic, aromatic, and heteroaromatic amines to
