Selective and multiple functionalization of C− H bonds can rapidly increase molecular complexity and expand chemical space. Particularly valuable are tandem reactions where directed C− H bond activation is combined with further functionalizations by careful control of reaction parameters. Herein, we report a catalytic protocol that couples α, β-desaturation of aliphatic cyclic carboxylic acids with subsequent vinyl C− H olefination and cyclization, providing a practical route for upgrading common aliphatic feedstock acids into diversified …
