A Pd(II)-catalyzed cascade synthesis of diverse polycyclic aromatic hydrocarbons via transient directing group strategy has been developed, involving the consecutive arylation, cyclization and aromatization. The efficiency and practicality were demonstrated by wide substrate range, concise synthetic pathway and mild reaction conditions. The subsequent transformations of the benz[a]anthracene core accessed
已经开发了一种通过Pd(II)催化的通过瞬态导向基团策略级联的多种多环芳烃,涉及连续的芳基化,环化和芳构化。广泛的底物范围,简明的合成途径和温和的反应条件证明了其效率和实用性。苯并[ a ]蒽核心的后续转化获得了天然的生物活性PAH分子。
