Synthesis of polycyclic lactams and sultams by a cascade ring-closure metathesis/isomerization and subsequent radical cyclization

Bressy, Cyril,Menant, Christine,Piva, Olivier

, p. 577 - 582 (2005)

Starting from readily available substrates, a new one-pot procedure has been devised to prepare polycyclic lactams and sultams. 2-Pyrrolines obtained from N,N-bisallylamides by ring-closure metathesis and subsequent isomerization promoted by ruthenium hyd
