    2-difluoroethene has been shown to be a diverse and highly effective building block for the preparation of a variety of fluorinated compounds. Reported here are preliminary results of its use for acylation reactions with acyl chlorides to form 2,2-difluoroketoacetamides as well as for its direct condensation with various acidic α-hydrogen carbon compounds to form a variety of functionalized difluoromethyl

    Synthetic utility of the novel difluoro ketene aminal 1 was extended to the preparation of a number of potentially biologically-interesting difluoro barbituric acid derivatives via initial hetero-Diels-Alder reactions of 1 with p-substituted-5-benzylidene-1,3-dimethylbarbituric acids 3. These cycloadducts 4 upon hydrolysis, provided the formal Michael addition product amides 5 which were readily converted to

    are assuming increasing importance as probes of biological function and enzyme mechanism. We now report a new, flexible route to enantiomerically pure L-4,4-difluoroglutamic acid that exploits the addition of difluorinated nucleophiles to configurationally stable alpha-aminoaldehydes. Conversion of the difluorinated adducts to L-4,4-difluoroglutamic acid can be accomplished in three steps by Barton-McCombie

  • Diverse Cycloaddition Chemistry Leading to Overall Michael Addition in the Reactions of 1,1-Bis(dimethylamino)-2,2-difluoroethene with α,β-Unsaturated Aldehydes, Ketones, Esters, and Nitriles
    作者:Yuelian Xu、William R. Dolbier
    DOI:10.1021/jo9710487
    日期:1997.9.1
    Difluoro ketene aminal 1 undergoes [2 + 4] cycloadditions with alpha,beta-unsaturated aldehydes and ketones and [2 + 2] cycloadditions with alpha,beta-unsaturated esters and nitriles. Both types of adducts can be readily converted, by mild hydrolysis, to the respective Michael addition products.
