SCHEME15: SYNTHESIS OF UNSUBSTITUTED PYRAZOLONE DERIVATIVES

Kadam et al. 34 have been repoted a novel synthesis of 3-amino-4-(4I-substituted benzylidene) - 1H-pyrazol-5(4H)-one derivatives 72 and 3-amino-4-(4I-substitued benzylidene) - 4, 5 - dihydro-5-oxopyrazole-1-carbothioamide derivatives 73 by the reaction of substituted benzaldehyde/ heteroaldehyde 70, ethylcyano acetate 71 and thiosemicarbazide was heated in presence of PEG-400.

SCHEME 1: SYNTHESIS OF C-TETHERED BISPYRAZOL-5-OLS

Ziarati et al. 42 have been reported simple and green process to prepare copper iodide in nano scale via sonication was carried out. Subsequently, this nanoparticles was used as an efficient catalyst for the synthesis of 2-aryl-5-methyl-2,3-dihydro-1H-3-pyrazolones 111 via four-component reaction of hydrazine 107, ethyl acetoacetate 108, aldehyde 109 and β-naphthol 110 in water under ultrasound irradiation.

Sivakumar et al. 39 have been reported an efficient synthesis of some Mannich base of 5-methyl-2-[(2-oxo-2H-chromen-3-yl) carbonyl]-2,4-dihydro-3H-pyrazol-3-one 95 have been described by using multicomponant with microwave techniques. Microwave assisted reactions showed that require shorter reaction time and good yield.

Antre et al. 40 have been reported various 4-(2-amino-6-(substituted)pyrimidin-4-yl)-3-methyl-1-(substituted)-1H-pyrazol-5(4H)-one derivatives 101 and their Schiff bases 102 were synthesized by the reaction of hydrazide 96 and ethylacetoacetate 97 to form pyrazolone derivatives 98. Compound 98 further react with acetyl chloride and prepared compound 99, therefore it has react with aromatic aldehyde and guanidine hydrochloride to gave pyrazolone derivatives 100 and 101. Afterthat pyrazolone derivatives 101 again react with aromatic aldehyde and formed pyrazolone Schiff base derivatives 102.
