7-Chloro-4-methyl-6-nitro-2H-chromen-2-one: a novel type of reagent for fluorescence analysis
摘要:
Starting from 7-chloro-4-methyl-2H-chromen-2-one 1 we have obtained a new reagent for fluorescence analysis. The synthesised key compound 7-chloro-4-methyl-6-nitro-2H-chromen-2-one 2 forms highly fluorescent derivatives with different amines, which can be introduced by nucleophilic substitution of the chloro atom. Two examples are given which describe the preparation of these derivatives. Additionally, we demonstrate that an increase of fluorescence can be achieved, if a reduction step is performed after the substitution. (C) 2003 Elsevier Science Ltd. All rights reserved.
