1‐Phényl, 2‐Pyrazolines Substituées

Abstract

Par réaction de la phénylhydrazine avec des chalcones et des analogues furaniques et thiéniques des chalcones, l'auteur a synthétisé des 1‐phényl, 2‐pyrazolines substituées en positions 3 et 5, par des groupements aryl, furyl et thiényl.

Synthesis, characterization and antimicrobial evaluation of 1-((5,3-diaryl)-4,5-dihydro-1H-pyrazol-1-yl)propan-1-one

“…Of particular interest is the use of 1H-pyrazoles as synthetic intermediates for preparing cyclopropane [17][18][19] and pyrazole derivatives [1,[20][21][22][23][24][25][26]. 1H-Pyrazoles have usually been prepared by starting from aldehydes or ketones, which have either actual or potential α,β-unsaturation [1,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. 1,3-Dipolar cycloadditions between diazoalcanes and different types of molecules containing activated double bonds are also exploitable reactions [1,16,17,42,43].…”
