The article was titled 《Organophotoredox catalytic four-component radical-polar crossover cascade reactions for the stereoselective synthesis of β-amido sulfones》, and you may find the article in Green Chemistry.Electric Literature of C20H20BrP The information in the text is summarized as follows:
Herein, a green and reliable strategy for the diastereoselective synthesis of β-amido sulfones R1S(O)2CH(R2)CH(Ar)NHC(O)R3 (R1 = Me, 4-methylphenyl, naphth-2-yl, etc.; R2 = H, Me, Et, Pr, isopropyl; Ar = Ph, 3,4-dichlorophenyl, naphth-2-yl, etc.; R3 = Me, cyclopopyl, Ph, etc.) and I through organophotoredox catalytic four-component radical-polar crossover cascade reactions was reported. This transformation features excellent atom-, step-, and redox economy and diastereoselectivity. Moreover, DFT calculation studies were performed to provide some insights into the origin of diastereoselectivity. In addition to this study using Ethyltriphenylphosphonium bromide, there are many other studies that have used Ethyltriphenylphosphonium bromide(cas: 1530-32-1Electric Literature of C20H20BrP) was used in this study.
Ethyltriphenylphosphonium bromide(cas: 1530-32-1) is a phase transfer catalyst, used to accelerate the cure of phenolic-based epoxy resins, certain fluoroelastomer resins and thermosetting powder coatings. It is also used as catalysts in the synthesis of certain organic compounds and as a pharmaceutical intermediate.Electric Literature of C20H20BrP
