Synthesis and Fluorescence Analysis of 3-Substituted 7-Dialkylamino-2H-1,4-benzoxazin-2-ones

New benzoxazinone type dyes have been synthesized by the reaction of α-keto esters on 2-amino-5(dialkylamino)phenols The obtained 7-dialkylamino-2H-1,4-benzoxazin-2-ones show a strong fluorescence and a large Stokes shift, reaching 183 nm.An effect of 15

Synthesis and Properties of Some 7-Dimethylamino-1,4-benzoxazin-2-ones

The synthesis of the 7-dimethylamino-1,4-benzoxazin-2-ones (5), fluorescent dyes, by condensing α-ketoacids with 2-amino-5-dimethylaminophenol is described.When the 3-substituent is a methyl group, these compounds can be further condensed with aromatic aldehydes to provide the styryl dyes (6).These products are easily opened by hydrochloric acid in ethanolic solution to afford the corresponding benzalketoacid ethyl esters (7).
