It has been found that N-alkylpyrrolidones do not undergo the Mannich reaction. Reaction is observed only following the introduction of an acetyl group at the pyrrolidone ring nitrogen (lla-c). However, replacement of the carbonyl group by thiocarbonyl increases C--H acidity in the 2-thiopyrroiidones, with the result that the 2-thiopyrrolidone (Ib) reacts with formaldehyde and secondary amines (dimethylamine
