A modified method to prepare 1,3,5-triarylpyridines by a [3+2+1] ring annulation reaction is described. Three-component condensation of neat reactants when subjected to microwaves afforded the required product in shorter reaction time with higher yield in
Studies on Cycloimmonium Ylides. Synthesis of Some 2,4,6-Triaryl-Substituted Pyridines via Isoquinolinium Ylides
(Aroylmethylene)isoquinolinium ylides on their reaction with different α,β-unsaturated ketones gave a wide variety of 2,4,6-triaryl-substituted pyridines which are expected to possess some potential biological activities.The reaction seemed to proceed via
