Cu(I) catalyzed alkyne-azide cycloaddition reaction was employed to synthesize a series of anthracene-based human thymidylate synthase (hTS) inhibitor analogues. The triazolo-anthracene derivatives were characterized by ESI-MS/MS and a novel rearrangementreaction in ESI-MS/MS was observed. The mechanism is proposed whereby the protonated triazolo-anthracene derivative forms a carbocation, and then

Fluorogenic reactions have broad applications in biolabeling, combinatorial synthesis of fluorescent dyes, and materials development. It was recently reported that the highly selective and efficient Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction can be employed in designing new types of fluorogenic reactions. In this study, we report a fluorogenic reaction using anthracene azides as starting materials. The fluorescence of the anthryl core can be greatly inhibited upon introducing electron-donating azido groups in the proximity. Such weakly fluorescent anthracene azides demonstrate high reactivity with a variety of alkynes under the CuAAC conditions producing a strongly fluorescent triazole product with high quantum yields. This reaction can be used in the synthesis and screening of fluorescent dyes combinatorially. Compared with most existing methods, the fluorogenic CuAAC reaction is a much milder and simpler technique to prepare large libraries of fluorescent dyes without further purification. In order to demonstrate the efficiency of using anthracene azides for biolabeling applications, both small molecules and biomolecules including the multialkyne-derivatized cowpea mosaic virus and tobacco mosaic virus had been studied.
