Mumford, Emily M.; Hemric, Brett N.; Denmark, Scott E. published an article in 2021. The article was titled 《Catalytic, Enantioselective Syn-Oxyamination of Alkenes》, and you may find the article in Journal of the American Chemical Society.Product Details of 1530-32-1 The information in the text is summarized as follows:
The chemo-, regio-, diastereo-, and enantioselective 1,2-oxyamination of alkenes R1CH=CHR2 (R1 = n-Pr, Ph, thiophen-3-yl, naphthalen-2-yl, etc.; R2 = i-Pr, (benzyloxy)methyl, (1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)methyl, etc.) using selenium(II/IV) catalysis with a chiral diselenides I (R = tert-Bu, Ph, adamantan-2-yl , naphthalen-2-yl) catalyst is reported. This method uses N-tosylamides R3C(O)NHTs (R3 = 2,6-dimethylphenyl, 2-bromophenyl, naphthalen-1-yl, etc.) to generate oxazoline products syn-II that are useful both as protected 1,2-amino alc. motifs and as chiral ligands. The reaction proceeds in good yields with excellent enantio- and diastereoselectivity for a variety of alkenes and pendant functional groups such as sulfonamides, alkyl halides, and glycol-protected ketones. Furthermore, the rapid generation of oxazoline products syn-II are demonstrated in the expeditious assembly of chiral PHOX ligands as well as diversely protected amino alcs. The results came from multiple reactions, including the reaction of Ethyltriphenylphosphonium bromide(cas: 1530-32-1Product Details of 1530-32-1)
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. CatOnium ETPB is also used as catalysts in the synthesis of certain organic compounds.Product Details of 1530-32-1
