Synthesis and Structure of 5-(2-Alkoxy-2-oxoethyl)-1,2-diaryl-4-hydroxy-1H-pyrrole-3-carboxylic Acid Esters
摘要:
Dialkyl 3,4-dihydroxyhexa-2,4-dienedioates reacted with substituted anilines and aromatic aldehydes or with the corresponding Schiff bases to give 5-(2-alkoxy-2-oxoethyl)-1,2-diaryl-4-hydroxy-1H-pyrrole- 3-carboxylates.

Reaction was studied of 3,4-dihydroxyhexa-2,4-diene-1,6-dioic acid esters with 2,4-dinitrophenylhydrazine that led to the formation of esters of (3E)-3-[2-(2,4-dinitrophenyl)-hydrazinylidene]-4-oxohexane-1,6-dioic and (3E,4E)-3,4-bis[2-(2,4-dinitrophenyl)hydrazinylidene]-hexane-1,6-dioic acids. The structural features of compounds synthesized were established from the data of IR and NMR spectra and
