An efficient, general, and convenient protocol for the synthesis of functionalized 9-amino-10-arylphenanthrene derivatives using a catalyst-free cascade reaction of arylboronic acids and 2′-cyano-biaryl-2-aldehyde N-tosylhydrazones is described. The synthesis was carried out via simple experimental conditions using Na2CO3 in 1,4-dioxane as a solvent. Moreover, the 9-amino-10-arylphenanthrene compounds
描述了使用芳基硼酸和2'-氰基-联芳基-2-醛N-甲苯磺酰基hydr的无催化剂级联反应合成官能化的9-氨基-10-芳基菲衍生物的有效,通用和方便的方案。通过在1,4-二恶烷中的Na 2 CO 3作为溶剂,通过简单的实验条件进行合成。此外,还以克级获得9-氨基-10-芳基菲化合物,并进一步衍生化以合成稠合的菲衍生物。
