protocol to synthesize 3,4’‐biquinolinesfrom2‐aminochalcones in the presence of a stoichiometric amount of sodium tert‐butoxide as the nucleophilic promotor was developed. Conjugate addition of tert‐butoxide to 2‐aminochalcones provided the corresponding enolates, which underwent Michael addition to another molecule of 2‐aminochalcone to afford a dimeric species of 2‐aminochalcones.

Fused triazoloquinolines have been prepared starting from (E)-3-(2-nitrophenyl)-1-aryl-prop-2-en-1-ones and sugar or benzyl azides in a sequential [3+2] cycloaddition reaction, followed by one pot Pd-C assisted reduction, cyclization and aromatization. The triazolyl fused quinolines with N-1-glycosyl substituents as unnatural nucleosides have inherent potential to generate a library of compounds for bioevaluations. (C) 2013 Elsevier Ltd.
