4-acyl-5-hydroxy-1-phenyl-3-trifluoromethyl-pyrazoles: Synthesis and nmr spectral investigations
Bieringer, Sabine,Holzer, Wolfgang
, p. 1825 - 1836 (2006)
The title compounds were prepared by reaction of 1-phenyl-3-trifluoromethyl-1H-pyrazol-5-ol with trimethyl orthoacetate, triethyl orthopropionate and triethyl orthobenzoate, respectively, followed by hydrolytic cleavage of the primarily formed condensatio

An experimental technique, ultrasound-static heating, has been developed for the efficient synthesis of heterocyclic compounds. The technique involves ultrasonic irradiation and static heating processes. First, the ultrasonic irradiation process is performed to form an intermediate of the heterocyclic compound under mild conditions and the subsequent static heating process (heating the intermediate under solvent-free conditions without stirring) produces the target heterocyclic compounds via intramolecular elimination.
Nitrogen's reactivity of various 3-alkoxypyrazoles
Guillou, Sandrine,Bonhomme, Frédéric J.,Janin, Yves L.
experimental part, p. 2660 - 2668 (2009/06/20)
Our current interest in the design of original chemical libraries featuring a pyrazole nucleus led us to focus on the chemistry of the 3-alkoxy-5-methylpyrazoles we have recently made readily available. With in mind the preparation of an array of the less
