multiple cascade reactions for the divergent assembly of fused N-heterocycles, comprising sequential activation of C–H and C–C bonds. Isolatable indene-type intermediates might be responsible for the generation of densely substituted fused pyridines, azepines, and azafluorenones products. The tolerance of strongly coordinating N-heterocycles, and those readily applicable for the late-stage modifications
简化从丰富的原料中产生多种高度功能化分子的过程,在药物和材料发现方面具有巨大的合成前景和挑战。本文中,我们报道了在多个级联反应中,对于稠合的N-杂环的发散组装,存在可调的选择性,包括C–H和C–C键的顺序激活。可分离的茚型中间体可能负责生成密集取代的稠合吡啶,氮杂ze和氮杂芴酮产品。强配位N-杂环的耐受性以及易于应用于药物和材料分子前体后期修饰的N-杂环的耐受性进一步证明了这种转化的合成稳健性。
