Examination of the Dipolarophilicity of Ethylene and Nitrile Functions in the Cycloaddition of Mesitonitrile Oxide to Isopropylidenemalononitrile

Lianis, P. S.,Rodios, N. A.,Alexandrou, N. E.

, p. 1683 - 1686 (2007/10/02)

Mesitonitrile oxide reacts with isopropylidenemalononitrile to give mono- and bis-1,2,4-oxadiazole derivatives 2 and 3 and Δ2-oxazolines 4 and 5 in moderate yields.The dipolarophilic character of the ethylene and nitrile functions in these cycl
