A Pericyclic Cascade in the Addition of Diphenyl Nitrile Imine to Pyridine
摘要:
On refluxing in benzene in the presence of excess pyridine the monocycloadduct of diphenyl nitrile imine to pyridine smoothly undergoes a [1,5] sigmatropic shift and a subsequent electrocyclic opening to afford 1,2,4-triazole derivatives.
