Resumo

Π-Excessive heterocycles react rapidly with bis(dialkylamino)methanes (aminals) and alkoxydialkylaminomethanes (aminol ethers) in acetonitrile to afford Mannich bases in good yields when activated by means of an acidic reagent such as acetyl chloride or sulphur dioxide: the principal compound studied was N-methylpyrrole.
