Synthesis of Lactones via C–H Functionalization of Nonactivated C(sp3)–H Bonds
摘要:
An electron-deficient amide is utilized as a directing group to functionalize nonactivated C(sp(3))-H bonds through radical 1,5-hydrogen abstraction. The gamma-bromoamides formed are subsequently converted to gamma-lactones under mild conditions. The method described is not limited to tertiary and secondary positions but also allows functionalization of primary nonactivated sp(3)-hybridized positions in a one-pot sequence. In addition, the broad functional group tolerance renders this method suitable for the late-stage introduction of gamma-lactones into complex carbon frameworks.
