Phenacylpyridinium ylid reacts with some substituted benzylidene-2-acetothiophenes, benzylidene-4-chloroacetophenones and benzylidene-3-nitroacetophenones in the presence of ammonium acetate in methanol or glacial acetic acid to give 2-phenyl-4-substituted-phenyl-6-(2-thienyl)pyridines (5a-e), 2-phenyl-4-substituted-phenyl-6-(4-chlorophenyl)pyridines (5f-j) and 2-phenyl-4-substituted-phenyl-6-(3-nitrophenyl)pyridines (5k-m), respectively in fair to good yields.

(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
Studies on Cycloimmonium Ylids. Synthesis of some New 2,4,6-Triaryl-substituted Pyridines via Pyridinium, Picolinium and Isoquinolinium Ylids

, p. 953 - 955 (2007/10/02)
Reaction of pyridinium phenacylids and their picolinium and isoquinolinium counterparts with substituted benzylideneacetophenones gave a wide variety of 2,4,6-triaryl-substituted pyridines which are expected to have some potential biological activities.Ammonium acetate in glacial acetic acid was used as the cyclization agent.The structures of resulting pyridines are supported by nmr and ir spectral data.
