  A method for the C‐3 functionalization of 2‐oxindoles through the Lewis‐acid‐promoted opening of spiroepoxyoxindoles with allylsilanes to give Hosomi–Sakurai‐type products as well as spirocyclic oxindoles with all‐carbon quaternary centres has been developed. A formal synthesis of (±)‐physovenine was accomplished in five steps using this approach.
