Rhodium-Catalyzed Ring-Opening Hydroacylation of Alkylidenecyclopropaneswith Chelating Aldehydes for the Synthesis of γ,δ-UnsaturatedKetones

The first intermolecular ring-opening hydroacylation of alkylidenecyclopropanes with chelating aldehydes through a rhodium-catalyzed acrylamide-promoted protocol is reported. This highly efficient ...
