  Dimerization of 2-pyridylisonitriles produces π-extended fused heteroarenes useful as highly selective colorimetric and optical probes for copper ion

  摘要：

  A very simple synthesis of pyrido[2 '',1 '':2',3']imidazo[4',5':4,5]imidazo[1,2-a]Pyridines 2 was achieved from the dimerization of 2-pyridylisonitriles. The optical responses of these pi-extended fused heteroarenes to a series of metal ions were investigated by means of UV-visible absorption spectrum in acetonitrile. It was found that most of compounds 2 selectively responded to Cu2+, and the limit of detection was about 3.5 x 10(-7) M when using the best probe, 3,9-dimethylpyrido[2",1":2',3']imidazo[4',5':4,5] imidazol1,2-a]pyridine 2d. Meanwhile some compounds 2 specifically showed a color change from colorless to red or yellow when they are exposed to copper ion in acetonitrile, whereas other transitional, alkali and alkaline earth metal ions could not induce a color change. This work not only established a direct access to pi-extended fused heteroarenes, but also supplied novel sensitive and selective colorimetric and optical probes for copper ion.

  silver‐catalyzed chemoselective [4+2] annulation of aryl and heteroaryl isocyanides with α‐substituted isocyanoacetamides was developed for the facile and efficient synthesis of 2‐aminoquinolones, naphthyridines, and phenanthrolines. A mechanism for this multistep domino reaction is proposed on the basis of a 13C‐labeling experiment, according to which an unprecedented chemoselective heterodimerization
