reaction pathways of a wide variety of tethered alkenes can be accessed through changing the amide directing group. This provides an efficient route to a myriad of complex polycyclic products, many containing newly formed all‐carbonquaternary centers. Amidoarylations can diastereoselectively deliver products with up to three contiguous stereocenters.

nickel-catalyzed removal of alkene protection group under mild condition with high functional group tolerance through chain walking process has been established. Not only phenolic ethers, but also alcoholic ethers can be tolerated with the retention of stereocenter adjacent to hydroxyl group. The new reaction brings the homoallyl group into a start of new type of protectinggroup.
