Modular synthesis of dihydro-isoquinolines: palladium-catalyzed sequential C(sp(2))–H and C(sp(3))–H bond activation

An efficient synthesis of dihydro-isoquinolines via a Pd–catalyzed double C–H bond [a C(sp(2))–H and a C(sp(3))–H bond] activation/annulation (CHAA) reaction is presented. This methodology features a short reaction time, high atom economy (loss of H(2)O only) and the formation of a sterically less f...

Sumario:An efficient synthesis of dihydro-isoquinolines via a Pd–catalyzed double C–H bond [a C(sp(2))–H and a C(sp(3))–H bond] activation/annulation (CHAA) reaction is presented. This methodology features a short reaction time, high atom economy (loss of H(2)O only) and the formation of a sterically less favoured tertiary C–N bond. This fast (30 min) and environmentally benign radical C–H activation approach has demonstrated the potential direction for the future design/development of fast and efficient C–H direct functionalization processes.
