Abstract

The Mannich reaction was applied to 3-isopropyltropolone and 3-isopropyl-5, 7-dimorpholinomethyl, and 3-isopropyl-5, 7-dipiperidinomethyltropolone were obtained. These substituents were easily substituted by diazonium salt or bromine. Some of the Mannich bases obtained were found to retain the zwitterion structure in the solid state.
