Double 1,3-Dipolar Cycloadditions of Meso-ionic Heterocycles to N-Substituted Maleimides

Double 1,3-dipolar cycloadditions of 2,4-diphenyl-3-methyloxazolium 5-oxide and 3-phenylsydnone to two molecules of N-substituted maleimide afforded one or two isomeric 4,8-iminobenzodipyrrole-1,3,5,7-tetrone derivatives owing to the types of heterocycles as well as N-substituents of maleimides.

CYCLOADDITION REACTION OF SYDNONE AND MALEIMIDE

The cycloaddition of sydnone to maleimide afforded exclusively two isomeric 1:2-adducts.This bifunctional character of sydnone allows its reaction with bismaleimides to form novel polyimides.
