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, 1111-67-7, name is Cuprous thiocyanate, introducing its new discovery. Recommanded Product: 1111-67-7
Enantioselective Organocatalyzed Direct alpha-Thiocyanation of Cyclic beta-Ketoesters by N -Thiocyanatophthalimide
A new electrophilic thiocyanation reagent, N-thiocyanatophthalimide, was synthesized and applied to the first example of catalytic asymmetric electrophilic alpha-thiocyanation of various cyclic beta-ketoesters by the bifunctional cinchona alkaloid catalysis. Thus, a variety of chiral alpha-thiocyanato beta-ketoesters with a quaternary carbon center have been achieved in excellent yields (up to 99%) and high enantioselectivities (up to 94% ee) in a convenient manner.
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 1111-67-7, help many people in the next few years.Recommanded Product: 1111-67-7
