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, 226942-29-6, name is 6-Bromo-1,2,3,4-tetrahydroisoquinoline, introducing its new discovery.

An efficient Lewis acid-catalyzed C(sp3)?C(sp3) bond forming annulation reaction has been developed. This strategy serves as a new method for the facile synthesis of tetrahydro-5H-isoquinolino[2,1-g][1,6]naphthyridine derivatives. A wide range of 2-methylquinoline-3-carbaldehydes and 1,2,3,4-tetrahydroisoquinolines can be applied for this process to afford structurally diverse tetrahydroprotoberberine derivatives in excellent yields. (Figure presented.).
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Reference of 226942-29-6. In my other articles, you can also check out more blogs about 226942-29-6
