The structure of the main product of the reaction when aniline is added to pyruvic acid is the tetrahydroquinoline lactone (2). When the reaction is carried out by adding the acid to aniline, a crystalline substance is obtained whose methyl ester has probably the structure (8). This methyl ester on acid treatment cyclized to 2,4-dimethoxycarbonyl-2-methyldihydroquinoline (10).
