1-Amino-3-phosphonopyrroles were prepared by direct reaction between conjugated azoalkenes and dimethyl (2-oxopropyl)phosphonate while the treatment of conjugated azoalkenes with diethyl cyanomethylphosphonate gives 1,2-diamino-3-phosphonopyrroles or 3a-phosphono-1,3a,6,6a-tetrahydropyrrolo[2,3-b]pyrroles, depending on the molar ratios of the reagents.
