routes have been developed to construct its skeleton. However, synthesis of unsymmetric phenanthrenes remains a challenge. Here, an efficient one-pot tandem reaction for the preparation of phenanthrenes via sequential γ-C(sp2)–H arylation, cationic cyclization, dehydration, and 1,2-migration was developed. A wide range of symmetric and unsymmetric phenanthrenes with diversified functional groups were synthesized
菲是化学和材料科学中的重要结构基序,并且已经开发出许多合成途径来构建其骨架。然而,不对称菲的合成仍然是一个挑战。在这里,开发了一种有效的一锅串联反应,用于通过顺序的γ-C(sp 2)-H芳基化,阳离子环化,脱水和1,2-迁移制备菲。合成了具有多种官能团的多种对称和不对称菲,收率良好。
