✦ Synopsis

1.2-1ndanediones are a new class of fluorogenic reagents for amino acid visualization. In order to better understand the mechanism of tormation of the resulting fluorescent products, we have examined the reactions of 1,2indanediones with amino compounds. Treatment of 1,2-indanedione with 3.5-dimethoxyaniline in benzene afforded several products. The initial mode of addition occurred through attack of nitrogen at the C-2 position of the 1.2indanedione generating an enamine which underwent subsequent reactions.
