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.
The invention provides compounds, pharmaceutical compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with abnormal or deregulated TRK kinase activity.
