介绍了一种在温和条件下, 利用苯炔与邻芳基甲酰苯乙腈串联反应构建9-氰基蒽衍生物的新方法. 以2-(三甲基硅)苯基三氟甲烷磺酸酯为苯炔前体, 以KF/18-C-6为氟源, tBuONa为碱, 原位生成的苯炔与邻芳基甲酰苯乙腈发生碳亲核进攻引发的串联环化/芳构化反应, 以47%~95%的产率合成了20种不同取代基团的9-氰基蒽衍生物.

关键词: 苯炔, 邻芳基甲酰苯乙腈, 9-氰基蒽

A new method for constructing 9-cyanoanthracene compounds by reacting aryne with ortho-arylformylphenyl-acetonitrile under mild conditions was introduced. Using 2-(trimethylsilicone)phenyltrifluoromethanesulfonate as the aryne precursor, KF/18-C-6 as the fluorine source, and tBuONa as the base, the aryne in situ generated can undergo a tandem cyclization/aromatization reaction triggered by carbon nucleophilic attack with ortho-arylformylphenylacetonitrile, and 20 differently substituted 9-cyanoanthracene products were synthesized in 47%~95% yields.

Key words: aryne, ortho-arylformylphenylacetonitrile, 9-cyanoanthracene
