  Intramolecular Hydroamination of Difluoropropargyl Amides:  Regioselective Synthesis of Fluorinated β- and γ-Lactams

  摘要：

  Functionalized gem-difluoro beta- and gamma-lactams were synthesized through a novel intramolecular hydroamination reaction of difluoropropargyl amides.beta-Lactams were obtained via a Baldwin disfavored 4-exo-digonal cyclization using palladium acetate as the catalyst, whereas gamma-lactams were produced under basic conditions. Acid hydration of gamma-lactams produced ketoamides or hemiaminals selectively.

  of 2,2-difluorohomopropargyl esters was achieved using a magnesium-promoted Barbier reaction of substituted difluoropropargyl bromides with alkyl chloroformates. These 2,2-difluorohomopropargyl esters were effective precursors in the synthesis of homopropargylic amidesby aminolysis using AlMe3, as well as of ketonesthrough the reaction of the corresponding Weinreb amides with Grignard reagents.

  使用取代基的二氟炔丙基溴化物与烷基氯甲酸酯的镁促进的Barbier反应，可实现2，2-二氟氟炔丙基酯的可扩展合成。这些2，2-二氟高炔丙基酯是通过使用AlMe 3进行氨解以及通过相应的Weinreb酰胺与Grignard试剂反应的酮合成高炔丙基酰胺的有效前体。使用二氟化的1,7-烯炔羰基化合物进行的闭环置换提供了六元二烯产物，将其用作狄尔斯-阿尔德反应的底物，得到4,4-二氟异喹啉-3-酮。炔烃与氟化的1,7-二炔酰胺的[2 + 2 + 2]环加成反应得到4,4-二氟-1,4-二氢-3（2 H）-异喹啉酮衍生物具有区域选择性。

  A dimerization of difluoropropargyl amides by reaction with gold(III) halides is described. A reductive elimination of a divinylgold species can be invoked to rationalize its formation. Initial studies of the unusual reactivity of these 1,4-dihalo-1,3-dienes have been performed.
