of azolo- and azinopyridines with varying substituents and annulated heterocycles were synthesized and examined in dearomatization reactions with carbon nucleophiles. Depending on the structure, the resulting covalent σ-adducts were formed either under basefree conditions or in Et3N-promoted process to give functionalized condensed dihydropyridines. Quantum-chemical calculations of the global electrophilicity
合成了许多具有不同取代基和环杂环的氮杂-和氮杂吡啶,并在与碳亲核试剂的脱芳香化反应中进行了检查。取决于结构,在无碱条件下或在Et 3 N促进的过程中形成生成的共价σ加合物,得到官能化的稠合二氢吡啶。由偶氮吡啶吡啶系列的FMO能量得出的整体亲电指数的量子化学计算用于解释对中性和阴离子C-亲核试剂的反应性。这些值对于特定反应模式的定性预测可能有用。
