LINEAR AND CYCLIC ETHYLENE-GLYCOLS LABELLED WITH NITROBENZOFURAZAN MOTIFS

NBD-chloride was used as a chromogenic and fluorogenic label to obtain three new derivatives, starting from 1,8-diamino-3,6-dioxaoctane, 4-aminobenzo-15-crown-5-ether and 4-aminobenzo18-crown-6-ether (compounds D-F, respectively). These compounds were compared with the corresponding derivatives obtained in a similar way, from NBD-chloride and 1-aza-18-crown-6-ether and 4,13-diaza-18-crown-6-ether (compounds A-C, respectively). UV-Vis, IR, NMR, fluorescence and MS spectra are discussed.

Automated summary
