A synthetic route for the preparation of unsymmetrically polysubstituted fluorenes was developed through the base‐catalyzed one‐pot domino reactions of aromatic ortho‐dialdehydes with 1,3‐dicarbonyl compounds. This protocol provides expeditious access to indene‐fused polycyclic aromatic hydrocarbons such as the benzo[b]fluorene and 13H‐indeno[1,2‐b]anthracene skeletons.
通过芳族邻二醛与1,3-二羰基化合物的碱催化单锅多米诺反应,开发了一种制备不对称多取代芴的合成途径。该协议可快速访问茚并稠合的多环芳烃,例如苯并[ b ]芴和13 H-茚并[1,2-b]蒽骨架。
