Synthesis of new steroid-β-lactam hybrids via palladium-catalyzed aminocarbonylation

Steroid-β-lactam and steroid-β-lactam-ferrocene conjugates were synthesized via palladium-catalyzed carbonylation of steroidal 17-iodo-16-enes in the presence of 3-amino-azetidin-2-ones. β-Lactam derivatives have been used for the first time as nucleophiles in the aminocarbonylation reaction. The products were obtained in good yields and were characterized by 1H and 13C NMR, IR and HRMS.
