SCHEME 6: SYNTHESIS OF 1-(FURAN-2-CARBONYL)-3-METHYL-4-(2-PHENYL HYDRAZONO)-1H-PYRAZOL-5(4H)-ONE BY MANNICH REACTION.

Mosaddegh et al. 24 heve been reported the synthesis of 4,4’-(arylmethylene)bis(3-methyl-1-phenyl-1H-pyrazol-5-ol) 27 was performed effectively by the reaction of aryl aldehydes 26 and 1-phenyl-3-methyl-5-pyrazolone 25 in the presence of a catalytic amount of Ce(SO4)2.4H2O as reusable and environmentally friendly catalyst in water/ethanol solution. The method has the advantages of high yields, short reaction time, simple work-up and reusability of catalyst.

Konkov et al.27 have been reported various pyrazole and dihydropyrazolones containing an adamantane fragment were synthesized from adamantyl-substituted 1,3- and 1,4-diketones, ethyl 4-(1-adamantyl)-2-R-4-oxobutanoates (R=CN, Ac), and ethyl 2-(1-adamantylcarbonyl)-4-oxo-4-phenylbutanoate. Compound 37 reacted with hydrazine and phenylhydrazine to give 4-[2-(1-adamantyl)-2-oxoethyl]-3-methyl-4,5-dihydro-1H-pyrazol-5-ones 38.
