| dc.description.abstract | In this work, the intramolecular C–H insertion of diazoacetamides catalyzed by dirhodium(II) complexes and using CO2 as solvent is disclosed. The expected lactams were obtained in yields over 97%. The asymmetric intramolecular C–H insertion was also achieved and the β-lactam 14 was obtained in >97% yield and 65% ee using the chiral dirhodium(II) catalyst Rh2(S-PTTL)4. Finally, the dirhodium(II) complex Rh2(OAc)4 was used in two consecutive cycles in which complete conversion to the lactam was observed. | por |
