New Advances in Chemical Research in 2021. In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 3340-78-1, name is 2-Phenyl-1,2,3,4-tetrahydroisoquinoline, introducing its new discovery. Recommanded Product: 3340-78-1
A cooperative photoredox and asymmetric catalysis for the enantioselective aerobic oxidative C(sp3)-H olefination of tetrahydro-beta-carbolines (THCs) is reported. This method, which is also effective for tetrahydroisoquinolines (THIQs), features a triple-catalyst strategy, involving a dicyanopyrazine-derived chromophore (DPZ) as the metal-free photoredox catalyst, a chiral Lewis base catalyst, and an inorganic salt cocatalyst. The current protocol provides straightforward access to a series of valuable alpha-substituted THCs and THIQs in high yields with excellent regio- and enantioselectivities (up to 95% ee).
