Stumpf, Andreas published the artcileSynthesis of 3-Aryl-Substituted 4-Aminopyrazoles from Acetophenones, Synthetic Route of 1468-83-3, the main research area is aryl substituted aminopyrazole preparation; acetophenone oximation condensation.
A synthetic methodol. for a protecting-group-free formation of 3-aryl-substituted 4-aminopyrazoles I [R = 4-MeOC6H4, 3-pyridyl, 3-thienyl, etc.] from acetophenones via a telescoped oximation and hydrazine condensation of 1,3-ketoaldehydes to generate nitrosopyrazoles, and copper-catalyzed NaBH4 reduction of the nitroso group, was demonstrated. The synthesis tolerated a broad scope of substrates with a variety of substituents on the Ph ring to afford the desired products.
Synthesis published new progress about Acetophenones Role: RCT (Reactant), RACT (Reactant or Reagent). 1468-83-3 belongs to class benzothiophene, name is 3-Acetylthiophene, and the molecular formula is C6H6OS, Synthetic Route of 1468-83-3.
