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.
Studies on Cycloimmonium Ylides. Synthesis of Some 2,4,6-Triaryl-Substituted Pyridines via Isoquinolinium Ylides
