  Synthesis of perfluoroalkylated indenes

  摘要：

  A series of perfluoroalkylated indenes has been synthesized using four different synthetic pathways. 1-(Pentafluoroethyl)indene and 2-(pentafluoroethyl)indene were prepared by the addition of (pentafluoroethyl)lithium to the appropriate ketones and subsequent dehydration. 2-(Trifluoromethyl)indene was synthesized through the photoinduced addition of trifluoromethyl iodide to indene, followed by dehydroiodination. 1-(Trifluoromethyl)indene was prepared by the addition of (trifluoromethyl)trimethylsilane to 1-indanone followed by deprotection and dehydration and by the sigmatropic cyclization of the appropriate phenylvinyl carbocation. This latter approach was also used to synthesize 1,3-bis(trifluoromethyl)indene and 1,2,3-tris(trifluoromethyl)indene.

  Reactions of 2-polyfluoroalkylchromones with (perfluoroalkyl)trimethylsilanes proceed as a 1,4-nucleophilic perfluoroalkylation to give 2,2-bis(polyfluoroalkyl)chroman-4-ones with high regioselectivity and good yields after acid hydrolysis. Oxidation of 6-methyl-2,2-bis(trifluoromethyl)chroman-4-one with a mixture of K2S2O8 and CuSO4 in aqueous acetonitrile leads to fluorinated analogues of natural lactarochromal and the corresponding acid. Reduction of substituted 2,2-bis(trifluoromethyl)chroman-4-one with sodium borohydride in methanol and subsequent dehydration of chromanols in refluxing xylene in the presence of p-toluene sulfonic acid gives 2,2-bis(trifluoromethyl)chromenes, which are fluorinated analogues of natural precocenes.

  A combination of readily available and bench‐stable CF3SO2Na and tBuOOH was efficiently used for hydrotrifluoromethylation of alkynes. An excellent trans‐selectivity was demonstrated in the synthesis of alkenes. The developed mild reaction conditions allow the supression of the competing Meyer–Schuster‐type rearrangement.
