Abbas, Zaheer published the artcileChiral ferrocene/indole-based diphosphine ligands for Rh-catalyzed asymmetric hydrogenation of functionalized olefins, HPLC of Formula: 617-52-7, the publication is Tetrahedron Letters (2020), 61(20), 151860, database is CAplus.
Convenient synthesis of a new family of chiral ferrocene/indole-based diphosphine ligands, (Rc,Rp)-IndoFerroPhos (L), from (Sc,Rp)-PPFA and 2-(diphenylphosphino)indole has been described. These new ligands exhibited high efficiency in the Rh-catalyzed asym. hydrogenation of functionalized olefins including α-dehydroamino acid esters, α-enamides and di-Me itaconate, in which up to >99% yield and 98% ee were achieved.
Tetrahedron Letters published new progress about 617-52-7. 617-52-7 belongs to esters-buliding-blocks, auxiliary class Alkenyl,Aliphatic hydrocarbon chain,Ester, name is Dimethyl itaconate, and the molecular formula is C7H10O4, HPLC of Formula: 617-52-7.
