In heterogeneous catalysis, the catalyst is in a different phase from the reactants. name: 6,7-Dimethoxy-1-methyl-3,4-dihydroisoquinoline, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 4721-98-6, name is 6,7-Dimethoxy-1-methyl-3,4-dihydroisoquinoline. In an article，Which mentioned a new discovery about 4721-98-6
The asymmetric transfer hydrogenation of imines was performed with the use of a polymer-immobilized chiral catalyst. The chiral catalyst, prepared from crosslinked polystyrene-immobilized chiral 1,2-diamine monosulfonamide, was effective in the asymmetric transfer hydrogenation of N-benzyl imines in CH 2Cl2 to give a chiral amine in high yield and good enantioselectivity. Furthermore, an amphiphilic polymeric catalyst prepared from crosslinked polystyrene containing sulfonated groups successfully catalyzed the asymmetric transfer hydrogenation of cyclic imines in water. Enantioenriched secondary amines with up to 94% ee were obtained by using a polymeric catalyst.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4721-98-6, help many people in the next few years.name: 6,7-Dimethoxy-1-methyl-3,4-dihydroisoquinoline
