Reactions of 1,5-diaryl-4-heteroyl-3-hydroxy-3-pyrrolin-2-ones with arylamines and butylamine

摘要

1,5-Diaryl-4-[2-thienoyl(furanoyl)]-3-hydroxy-3-pyrrolin-2-ones reacted with aromatic amines to form arylamino-3-pyrrolin-2-ones. Reactions with butylamine occurred via intermediate salt formation followed by their transformation into 3-butylamino-3-pyrrolin-2-ones at heating.
