An efficient palladium-catalyzedC–H bond alkenylation/annulation strategy to access carboline carboxylates from indolyl ketoximes and acrylates through C–C/C–N bond formation is reported. Indolyl ketoximes not only direct ortho-olefination with acrylates, but also undergo an intramolecular N–O bond cleavage/traceless annulation to construct carboline carboxylates straightforwardly in this concise

AbstractThe rhodium(III)‐catalyzed oxidative annulations of aryl ketoximes with diphenylacetylene by the cleavage of three CH bonds, one CO bond and the formation of four CC bonds, one CN bonds simultaneously have been developed. This protocol is scalable and compatible with various functional groups, providing an expeditious access to highly congested polycyclic aromatic/heteroaromatic hydrocarbons.magnified image
