Unsubstituted β-aminoenones react with α-aminoderivatives by a well established route which implies a fast transamination process — 1,4-addition followed by elimination — and cyclodehydration of the intermediate to 3-functionalized pyrroles. In contrast, 3-dimethylaminoacrylaldehyde undergoes 1,2-addition followed by cyclization to give the final 2-substituted pyrroles. Isolation of the intermediates
