Steroid-β-lactam and steroid-β-lactam-ferrocene conjugates were synthesized viapalladium-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.
在3-氨基氮杂环丁烷-2-酮的存在下,通过钯催化的甾族17-碘-16-烯的羰基化反应合成了甾体-β-内酰胺和甾体-β-内酰胺-二茂铁共轭物。β-内酰胺衍生物首次在氨基羰基化反应中用作亲核试剂。以高收率获得产物,并通过1 H和13 C NMR,IR和HRMS进行表征。
