Rhodium(III)- and Ruthenium(II)-Catalyzed Olefination of Isoquinolones
摘要:
NH and N-protected isoquinolones undergo Rh(III)-catalyzed oxidative olefination at the 8-position. Complementary redox-neutral olefination of such isoquinolones using internal alkynes was achieved under ruthenium catalysis.
Cobaltacycle synthesis via C–H activation has been achieved for the first time, providing key mechanisticinsight into cobalt catalytic chemistry. N-Chloroamides are used as a directing synthon for cobalt-catalyzed room-temperature C–H activation and construction of heterocycles. Alkynes as coupling partners allow convenient access to isoquinolones, a class of synthetically and pharmaceutically important
