Reported herein is a palladium-catalyzed secondary benzylic imidoylative Negishi reaction leveraging the sterically bulky aromatic isocyanides as the imine source. This method allows the facile access of alkyl-, (hetero)aryl-, and alkynylzinc reagents to afford various α-substituted phenylacetone products under mild acidic hydrolysis, which are ubiquitous motifs in many pharmaceuticals and biologically
本文报道了利用空间上庞大的芳族异氰酸酯作为亚胺源的钯催化的仲苄基亚氨基酰亚胺化Negishi反应。该方法允许在温和的酸性水解条件下容易地获得烷基,(杂)芳基和炔基锌试剂,从而得到各种α-取代的苯丙酮产物,这些产物是许多药物和生物活性化合物中普遍存在的基序。亚胺的非对映选择性还原可以实现,以将仲苄基卤化物方便地转化为具有高原子经济性的α-取代的苯乙胺衍生物。
