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.

3-Phenylsydnone and 2,4-diphenyl-3-methyloxazolium 5-oxide undergo double 1,3-dipolar cycloadditions with two molecules of N-phenylmaleimide to produce 4,8-iminobenzodipyrrole-1,3,5,7-tetrone derivatives in a stereoselective manner.
