1,3-Dipolar Cycloaddition Reactions of 4-Arylidene-2-phenyl-1,4-dihydroimidazol-5-ones with Nitrile Oxides
Argyropoulos, N. G.,Coutouli-Argyropoulou, E.,Siacavara, C.
, p. 2097 - 2100 (2007/10/02)
Stable nitrile oxides add regioselectively to the carbon-carbon double bond of 4-arylidene-2-phenyl-1,4-dihydroimidazol-5-ones to afford spiro isoxazolines 3.Compounds 3 are further hydrolysed to isoxazole derivatives.
