  Synthesis of novel 2-perfluoroacylcyclohexane-1,3-diones

  摘要：

  A one-pot synthesis of 2-perfluoroalkanoylcyclohexane-1,3-diones via C-acylation of cyclohexane-1,3-diones with N-perfluoroacylimidazole as an acylating agent is reported. A reaction was examined with isolated N-trifluoroacetylimidazole and with N-perfluoroacylimidazoles generated in situ from perfluorocarboxylic acid anhydrides or perfluorocarboxylic acids.

  Ionic hydrogenation of 2-perfluoroalkanoylcyclohexane-1,3-diones and their endocyclic enamino derivatives containing a secondary amino group by the action of triethylsilane in trifluoroacetic acid in the presence of a catalytic amount of lithium perchlorate involved regioselective reduction of the side-chain carbonyl group to hydroxy with formation of the corresponding hydroxy diketones and hydroxy amino ketones, respectively. Under analogous conditions endocyclic enamino derivatives possessing a tertiary amino group underwent deacylation to give enamino ketones.

  Reactions of 2-perfluoroalkanoylcyclohexane-1,3-diones with primary and secondary amines involved acid cleavage of the substrate with formation of the corresponding 3-aminocyclohex-2-en-1-ones. Vinylogous nucleophilic substitution in 3-chloro-2-perfluoroalkanoylcyclohex-2-ene-1-ones with amines led to the formation of 3-amino-2-perfluoroalkanoylcyclohex-2-ene-1-ones.

  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.
