OXAZOLONES. PART VI. REACTION OF 5(4H)-OXAZOLONES WITH NITRILE IMINES: SYNTHESIS OF 1H-1,2,4-TRIAZOLES THROUGH CYCLOADDITION
Gelmi, Maria Luisa,Pocar, Donato,Riva, Raul
, p. 315 - 320 (2007/10/02)
5(4H)-Oxazolones (1) react as dipolarophiles in cycloadditions with nitrile imines generated from tetrazoles (2) in refluxing anisole affording two 1H-1,2,4-triazole derivatives (3) and diarylethylenes (4).
