Rapid microwave-enhanced synthesis of 1-phenyl-3-methyl-5-Acyloxypyrazoles under solvent-free conditions
Bai, Yinjuan,Lu, Jun,Gan, Haiying,Wang, Zhenjun
, p. 2549 - 2553 (2002)
The microwave-enhanced synthesis of 5-acyloxypyrazoles from 1-phenyl-3-methylpyrazole-5-one and acid chlorides under solvent-free conditions has been achieved in moderate to good yield.
Antioxidant and acetylcholinesterase inhibition activity of aliphatic and aromatic edaravone derivatives
Barajas-Carrillo, Victor Wagner,Estolano-Cobián, Arturo,Díaz-Rubio, Laura,Ayllón-Gutiérrez, Rocío Rosario,Salazar-Aranda, Ricardo,Díaz-Molina, Raúl,García-González, Víctor,Almanza-Reyes, Horacio,Rivero, Ignacio A.,Marrero, Joaquín G.,Córdova-Guerrero, Iván

As Alzheimer disease (AD) is a multifactorial condition, it should be tackled with drugs targeting multiple key pathways. A series of aliphatic (2–8) and aromatic (9–15) edaravone derivatives were synthesized, characterized, and evaluated as antioxidant a
Synthesis of 1-acyl-1,2-dihydro-3H-pyrazol-3-ones via Lewis acid-mediated rearransement of 3-acyloxypyrazoles
Maruoka, Hiroshi,Yamagata, Kenji,Okabe, Fumi,Tomioka, Yukihiko
, p. 859 - 865 (2007/10/03)
The unusual formation of 1-acyl-1,2-dihydro-3H-pyrazol-3-ones starting from 3-acyloxypyrazoles by Fries-type rearrangement is described. Under normal conditions, acylation of 2,4-dihydro-3H-pyrazol-3-ones 1 and 2 with acid chlorides or anhydrides in the p
Structures of 1-Phenyl-3-methyl-pyrazolone-5- and its Benzoyl Derivatives

, p. 1019 - 1023 (2007/10/02)
The sturctures of 1-phenyl-3-methyl-pyrazolone-5 and its benzoyl derivatives have been investigated by means of IR, UV, NMR, and mass spectral spectroscopy. 1-Phenyl-3-methyl-pyrazolone-5-is found to exist as a zwitter ion in the solid state, in the 5-ket
