  Synthesis and spectroscopic investigation of the new polyfluoroalkyl-containing indazolones

  摘要：

  Reaction of 2-perfluoroacylcycloalkane-1,3-diones and their enol methyl esters with N,N-dinucleophiles such as 4-fluorophenylhydrazine hydrochloride and pentafluorophenylhydrazine results in formation of polyfluoroalkyl-containing 1-aryl-3-polyfluoroalkyl-6,7-dihydro-1H-indazol-4(5)H-ones and 2-aryl-3-polyfluoroalkyl-6,7-dihydro-2H-indazol-4(5)H-ones respectively. Structure of compounds obtained was proved with IR, H-1, H-13, F-19, N-15 NMR, and mass-spectrometric methods.

  An efficient protocol for the synthesis of novel lupane triterpenoid-indazolone hybrids with oxime ester linkage has been developed from naturally accessible precursor betulin. For the first time a series of betulonic acid-indazolone hybrids have been synthesized via an acylation of corresponding 6,7-dihydro-1H-indazol-4(5H)-one oximes with betulonic acid chloride. Diastereoselective reduction of the obtained betulonic acid conjugates with NaBH4 resulted in a formation of betulinic acid-indazolone hybrids in excellent yields. The configuration of the key compounds has been fully established by X-ray and 2D NMR analysis. (C) 2016 Elsevier Inc. All rights reserved.

  Refluxing 3-perfluoroalkyl-6,7-dihydro-1H-indazol-4(5H)-ones with 4-fold excess of hydroxylamine hydrochloride in pyridine afforded their (E)-oximes. The obtained oximes were alkylated with ethyl iodide and acylated with carboxylic acids chlorides to obtain (E)-O-alkyl- and (E)-O-acyloximes respectively. Heating oximes in PPA at 120A degrees C results in their aromatization by Semmler-Wolff reaction, hydrolysis of perfluoroalkyl groups, and generation of 4-amino-1-aryl-5,6-dimethyl-1H-indazole-3-carboxylic acids from of 3-tri-fluoromethylindazolone oximes and 1-(4-amino-1-aryl-5,6-dimethyl-1H-indazol-3-yl)-fluoroalkan-1-ones from of 3-perfluoroethyl- and 3-perfluoropropylindazolone oximes.
