Jana, Debasish published the artcileMannich reaction of pyrrole and dimethylpyrrole with monoamines and diamines, Synthetic Route of 10517-44-9, the publication is Tetrahedron Letters (2019), 60(46), 151247, database is CAplus.
The Mannich reaction of pyrrole with ethylenediamine dihydrochloride and formaldehyde gave two compounds: N1,N1,N2,N2-tetrakis(pyrrol-2-ylmethyl)ethane-1,2-diamine and 1,3-bis(pyrrol-2-ylmethyl)imidazolidine in poor yields. Conversely, the reaction of pyrrole with propylenediamine dihydrochloride afforded macrocyclic compound I in 50% yield. The reaction of 2,5-dimethylpyrrole with methylamine hydrochloride and formaldehyde gave novel bicycle II. The reaction of 2,5-dimethylpyrrole with ammonium chloride gave the tripodal ligand tris(2,5-dimethylpyrrol-3-yl)methylamine in 62% yield. The structures of 1,3-bis(pyrrol-2-ylmethyl)imidazolidine, I and II were determined by single crystal X-ray diffraction studies.
