ZnO-NP assisted synthesis of fluorescent beta-carboline C-1 tethered benzimidazole/benzothiazole/benzoxazole derivatives and assessment of their photophysical properties
A facile transformation of 1-formyl beta-carboline into fluorescent beta-carboline C-1 tethered benzazole derivatives is described under the catalysis of ZnO nanoparticles. The reaction proceeded with the reaction of 1-formyl beta-carboline and substituted o-diaminobenzene/2-aminobenzenethiol/2-aminophenol, which results in formation of a Schiff base, followed by an intramolecular cylization reaction to generate beta-carboline linked benzimidazole, benzothiazole and benzoxazole derivatives. This appraoch displayed a wide substrate scope and high regioselectivity to yield the desired products in moderate to good yields. The photophysical properties of the synthesized derivatives were also evaluated and they exhibited excellent fluorescence properties. Among these beta-carboline substituted azoles, the benzothiazole derivative displayed the maximum quantum yield (phi(F) up to 28%).
