The reactions of some conjugated azoalkenes with nitriles containing active methylene groups have been studied and, depending on the nature and the molar ratios of the reagents, new 1,2-diamino-3-cyanopyrroles, and symmetric and asymmetric 1,3a,6,6a-tetrahydropyrrolopyrroles can be obtained in good yields and under mild reaction conditions.The stereochemistry of one of the 1,3a,6,6a-tetrahydropyrrolopyrrole derivatives was investigated in detail by X-ray diffraction.
