highly enantioselective CuI-catalyzed reaction of tetrahydroisoquinolines (THIQs), alkynes, and 2-bromobenzaldehyde derivatives. This enables us to accomplish the first asymmetric total synthesis of 12 natural 13-methyltetrahydroprotoberberine (13-MeTHPB) alkaloids in only three catalytic steps with 47–64% overall yields. In addition, the Pd-catalyzed reductive Heck cyclization was successfully extended
