A new route has been reported for the synthesis of densely oxygenated polycyclic aromatic compounds via cycloaddition approach. This strategy involves the Dötz benzannulation and Diels-Alder reaction as key steps. Naphthalene synthons required here were generated by Dötz benzannulation between aryl chromium carbene complexes and symmetrical internal alkyne.
已经报道了通过环加成法合成高氧合多环芳族化合物的新途径。该策略涉及Dötz苯环和Diels-Alder反应作为关键步骤。此处所需的萘合成子是通过芳族铬卡宾配合物和对称内部炔烃之间的Dötz苯并环生成的。
