Whereas the intramolecular reductive Heck reaction of aryl/vinyl halide and alkene has been well documented, the oxime analogue remains extremely elusive. Herein we report the Pd(0)-catalyzed intramolecular reductive Heck reaction of vinyl iodide and oxime ether with the use of formic acid as the reductant. It is found that the TsOH additive plays a crucial role in the reaction efficiency, and the (S)-SEGPhos ligand enables cyclic allylic N-alkoxy amine products with high enantioselectivity.
