A Selective Rh-I-Catalyzed Substrate-Controlled C-C Bond Activation of Benzyl Sulfonamide/Alcohol-Tethered Alkylidenecyclopropanes

摘要

Benzyl sulfonamide/alcohol-tethered alkylidenecyclopropanes undergo a rhodium-catalyzed and substrate- controlled selective C-C bond activation, producing three types of common organic structural units: benzocazepine/oxepines, dihydronaphthalen-1-amines, and conjugated dienes. Epoxidation and aromatization of these products to construct two useful compounds have also been achieved.
