- Atom‐economical addition: RhIII‐catalyzed “Grignard‐type” cyclization between cyclic N‐sulfonyl ketimines and internal alkynes has been developed to afford multifunctional spirocyclic sultam products in high yields (up to 99 %) under mild conditions (see scheme, Cp* = pentamethylcyclopentadienyl, DCE = 1,2‐dichloroethane).
