英文摘要: A method for the synthesis of highly substituted pyridines from alpha,beta-unsaturated oximes and internal alkynes has been developed using [Cp*RhCl2](2)-CsOPiv as the catalyst system. The present transformation is carried out by a redox-neutral sequence of vinylic C-H rhodation, alkyne insertion, and C-N bond formation of the putative vinyl rhodium intermediate with the oxime nitrogen, where the N-O bond of oxime derivatives could work as an internal oxidant to maintain the catalytic cycle.
