  • Palladium-Catalyzed Site-Selective Amidation of Dichloroazines
    作者:Ian S. Young、Anna-Lena Glass、Theresa Cravillion、Chong Han、Haiming Zhang、Francis Gosselin

    日期:2018.7.6
    A highly site-selective amidation reaction of substituted 2,4-dichloroazines is reported. Palladium acetate/1,1′-bis(diphenylphosphino)ferrocene (dppf) was identified as the optimal catalyst system, producing >99:1 C-2/C-4 selectivity for most examples. The generality of this transformation was demonstrated through a survey of a diverse amide/substituted 2,4-dichloroazine scope, leading to the preparation
    报道了取代的2,4-二嗪的高度位点选择性酰胺化反应。乙酸/ 1,1'-双(二苯基膦基二茂铁(dppf)被确定为最佳催化剂体系,在大多数实例中,其生成的C> 2 / C-4选择性> 99:1。通过各种酰胺/取代的2,4-二嗪范围的调查证明了这种转化的一般性,从而以良好至极好的收率制备了所需的C-2酰胺化产品。
