  Asymmetric Suzuki Cross-Couplings of Activated Secondary Alkyl Electrophiles: Arylations of Racemic α-Chloroamides

  摘要：

  A nickel-catalyzed stereoconvergent method for the enantioselective Suzuki arylation of racemic alpha-chloroamides has been developed. This process provides a unique example of an asymmetric arylation of an alpha-haloamide, an enantioselective arylation of an alpha-chlorocarbonyl compound, and an asymmetric Suzuki reaction with an activated alkyl electrophile or an arylboron reagent. The method is also applicable to the corresponding enantioselective cross-coupling of alpha-bromoamides. The coupling products can be transformed without racemization into enantio-enriched alpha-arylcarboxylic acids and primary alcohols. A modest kinetic resolution of the alpha-chloroamide was observed; a mechanistic study indicated that the selectivity may reflect discrimination by the chiral catalyst of the two enantiomeric alpha-chloroamides in an irreversible oxidative-addition process.

  A Pd-catalyzed C–O cross-coupling of O-acyl hydroxylamines and tertiary or secondary alkyl electrophiles was reported without the cleavage of the rather fragile N–O bond. The described strategy provides direct access to congested N,N,O-trisubstituted hydroxylamines bearing an α-quaternary carbon center under mild conditions in high yields and features exclusively chemoselective C–O bond formation,

  据报道，Pd 催化的O-酰基羟胺和叔或仲烷基亲电子试剂的 C-O 交叉偶联没有裂解相当脆弱的 N-O 键。所描述的策略提供了在温和条件下以高产率直接获得带有α-季碳中心的拥挤的 N、N、O-三取代羟胺，并具有独特的化学选择性 C-O 键形成、广泛的底物范围和出色的官能团耐受性。交叉偶联的合成潜力是通过药物衍生化和一系列催化后修饰建立的。
