|Title:||A copper sulphate catalysed synthesis of derivatives of tetra substituted pyridine|
|Keywords:||Michael addition;copper-sulphate;unsaturated oxime solvent-system;tetra-substituted pyridine|
|Abstract:||Copper sulphate has been found to be an effective catalyst in water-ethanol solvent system for the synthesis of various tetra-substituted pyridine derivatives via Michael addition of -dicarbonyl compounds to ,-unsaturated oximes and subsequent ring closure. A rapid synthesis of heterocycles by this methodology is ecofriendly in nature in addition to remarkably improved yield and reduced reaction times.|
