3,4-Dimethyl-2,5-hexanedione and 2,5-hexanedione were reacted with model amines to yield N-substituted 2,3,4,5-tetramethylpyrroles and 2,5-dimethylpyrroles, respectively. When compared to the unsubstituted parent compound 2,5-hexanedione, 3,4-dimethyl-2,5-hexanedione was found to cyclize approximately eight times as rapidly on a molar basis at 37 degrees
