Abstract
AbstractBenzo[c]chromones are valuable tricyclic systems of natural and biological significance. Herein, we report a concise approach of 6,6‐disubstituted 6H‐benzo[c]chromenes in a two‐step sequence starting from ortho‐bromo benzylic alcohols and arylboronic acids, using intermolecular palladium‐catalyzed C−C and intramolecular N‐Iodosuccinimide (NIS) mediated key C−O bonds construction. Besides, the current method explored broad substrate scope under robust conditions. Notably, the practicality of the present approach is further extended for the total synthesis of Didehydroconicol.
