A new strategy for highly diastereoselective synthesis of furo[3,2-b]-beta-lactams and furo[3,2-b]-gamma-lactams via a novel Ag(I)-mediated intramolecular 1,3-dipolar cycloaddition of oxo-N-propargylamides, is developed and the possible mechanism of these transformation is proposed.
通过新颖的Ag(I)介导的分子内1,3-偶极环加成反应合成呋喃[3,2-b]-β-内酰胺和呋喃[3,2-b]-γ-内酰胺的非对映选择性的新策略研发了羰基-N-炔丙基酰胺,并提出了这些转化的可能机理。
