Abstract

Nickel(0)-Catalyzed [2 + 2 + 1] Carbonylative Cycloaddition of Imines and Alkynes or Norbornene Leading to -Lactams. -A key feature of the process is the use of phenyl formate as a CO source that enables carbonylation and prevents quenching of the catalyst. -(HOSHIMOTO, Y.; OHATA, T.; SASAOKA, Y.; OHASHI, M.; OGOSHI*, S.; J.
