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).
当将苯胺加到丙酮酸中时,反应的主要产物的结构是四氢喹啉内酯(2)。当通过将酸添加到苯胺中进行反应时,获得结晶物质,其甲酯可能具有结构(8)。经酸处理的该甲酯环化为2,4-二甲氧基羰基-2-甲基二氢喹啉(10)。
