Synthesis of 4-substituted 1,5-diaryl-3-diphenylmethoxy-3-pyrrolin-2-ones and their [1,5]-sigmatropic rearrangement
摘要:
Reactions of 1,4,5-trisubstituted 3-hydroxy-3-pyrrolin-2-ones with diphenyldiazomethane yield the O-alkylation products. Thermolysis of 1,5-diaryl-4-heteroyl-3-hydroxy-3-pyrrolin-2-ones is accompanied with suprafacial [1,5]-sigmatropic rearrangement.

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.
