The Mannich-type reaction for 1-methoxycarbonyl- or 1-benzyloxycarbonyl-2-methoxylpyrrolidine with carbon nucleophiles such as acetylacetone, methyl acetoacetate, dimethyl malonates, benzoylacetone, dibenzoylmethane, or cyclohexane-1, 3-dione proceeded by acid catalysis under solvent-free conditions with more efficiency than that in dichloromethane.
