摘要：
A convenient synthesis of tricyclic beta-lactams by chemo- and diastereoselective intramolecular CH insertion of metal carbenes generated by dirhodium(II) tetraacetate catalyzed decomposition of alpha-diazoamides 1a-c is reported. In the case of reagent 1b, in the presence of the (+)-menthyl chiral auxiliary, the beta-lactam is obtained with 76% e.e.
