- Microwave-assisted, solvent-free, three-component synthesis of 2,4,6-triarylpyridines from benign components
-
2,4,6-Triarylpyridine derivatives were synthesised by the reaction of guanidine with an acetophenone and a chalcone. These reactions were carried out as economical one-pot reactions under green conditions: no catalyst and solvent free.

- Microwave-promoted and Lewis acid catalysed synthesis of 2,4,6-triarylpyridines using urea as benign source of ammonia
-
An efficient method for the synthesis of 2,4,6-triarylpyridines via microwave-promoted and BF3·OEt2-catalysed one-pot reaction of ω-pyrrolidinoacetophenone with chalcone is reported. This method illustrates urea as an environmentally

- A novel and efficient 2,4,6-trisubstituted pyridine ring synthesis via α-benzotriazolyl ketones
-
Reaction of α-benzotriazolyl ketones with α,β-unsaturated ketones resulted in 2,4,6-triarylpyridines, 2,4-diaryl-5H-indeno[1,2-b]pyridines and 2,4-diaryl-5,6-dihydrobenzo[h]quinolines in good yields.

- Synthesis of Some New 2,4,6-Triarylpyridines Using Phenacylpyridinium Ylid
-
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.
