Synthesis of unsymmetrical polysubstituted pyridines from β-sulfonylvinylamines via 1-aza-allyl anion intermediates

A modular synthesis of highly functionalized unsymmetrical pyridines has been developed from reacting β-sulfonylvinylamines with α,β-unsaturated systems in the presence of base via the formation of 1-aza-allyl anion intermediates. Georg Thieme Verlag Stut

A new and convenient one-pot solid supported synthesis of 2,4,6-triarylpyridines

A new, convenient, efficient and cost-effective one-pot solid supported synthesis of 2,4,6-triarylpyridines from benzylideneacetophenones and urea, thiourea or their derivatives, using Bi(III) nitrate-Al2O3 is described. The reaction seems to proceed via β-oxygenation of Bi(III)-enolized benzylideneacetophenone followed by Michael addition, heteroannulation with simultaneous retro aldol disproportionation and subsequent catalytic oxidation and dehydration.

Synthesis of Some New 2,4,6-Triarylpyridines Using Phenacylidenedimethylsulfuranes

Phenacylidenedimethylsulfurane and p-chlorophenacylidenedimethylsulfurane were reacted with α,β-unsaturated ketones in the presence of ammonium acetate in glacial acetic acid to give 2,4,6-triarylpyridines in 45-70percent yields.The structures of the pyri

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.

Studies on Cycloimmonium Ylids: Synthesis of Some 2,4,6-Triarylpyridines via Isoquinolinium Ylids

Aroylmethylene-isoquinolinium ylids on reaction with substituted benzylidenacetophenones in gl. acetic acid containing ammonium acetate afford 2,4,6-triarylpyridines (4a-j).The reaction seems to proceed via the intermediacy of pentane-1,5-dionylisoquinoli
