The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 18437-78-0, Name is Tris(4-fluorophenyl)phosphine, SMILES is FC1=CC=C(P(C2=CC=C(F)C=C2)C3=CC=C(F)C=C3)C=C1, in an article , author is Gan, Zhenjie, once mentioned of 18437-78-0, Recommanded Product: 18437-78-0.
P-Stereogenic Phosphines Directed Copper(I)-Catalyzed Enantioselective 1,3-Dipolar Cycloadditions
A new pair of P-stereogenic ligands with multiple chiral centers were synthesized and used in the copper(I)-catalyzed enatioselective [3 + 2] cycloaddition of iminoesters with alkenes. A variety of highly functionalized pyrrolidines were obtained in excellent yield and enatioselectivity. This is the first example of a pair of P-stereogenic ligands working as pseudoenantiomers to tune the enantio- and diastereoselective 1,3-dipolar cycloaddition, and providing a pair of enantiomerically pure pyrrolidines, respectively.
