Practical Synthesis

This work discloses a novel and efficient protocol for the construction of functionalized chromeno[3,4-c]pyridine derivatives from the Blaise reaction intermediates and 3-cyanocoumarins through a CuCl2-catalyzed sequential Michael addition/intramolecular cyclization/oxidative aromatization reaction. This new method shows the advantages of mild reaction conditions, easy workup, nonchromatographic purification technique, good functional group tolerance, and moderate to good yields.

Oxadiazole Derivatives

Three 2,6-bis (1,3,4-oxadiazol-2-yl) pyridine derivatives were synthesized and their structures were conformed by1H NMR, FTIR, MS techniques and elemental analysis. The UV–Vis absorption and fluorescence emission spectra of these compounds were investigated in chloroform solution. The results showed that these bis-1,3,4-oxadiazole derivatives had broad and strong absorption at 278−302 nm in the UV–Vis spectra and exhibited fluorescence emission at 338 −367 nm under UV illumination in fluorescence spectra. It was found that the nature of the substituents at benzene ring in bis-1,3,4-oxadiazole derivatives had a significant impact on their photoluminescence behaviors.
