Ag-containing all-carbon 1,3-dipoles: Generation and formal cycloaddition for furo[3,2-b]-β/γ-lactams

Article abstract of DOI:10.1039/b917856b

A new strategy for highly diastereoselective synthesis of furo[3,2-b]-β-lactams and furo[3,2-b]-γ-lactams via a novel Ag(i)-mediated intramolecular 1,3-dipolar cycloaddition of oxo-N- propargylamides, is developed and the possible mechanism of these trans
