Abstract: A highly convergent one-pot synthesis of Hantzsch-type pyridines has been developed based on a three-component annulation of 1,3-dicarbonyl compounds, DMSO, and ammonium salt. A transition-metal-free oxidative methylenation reaction/Hantzsch pyridine synthesis cascade reaction was involved in… read more here.
