Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 503538-69-0, is researched, Molecular C38H24F4O4P2, about Enantioselective Ag-catalyzed allylation of aldimines, the main research direction is homoallylic amine enantioselective preparation; aldimine crotyl allyl trimethoxysilane enantioselective crotylation allylation; crotylation allylation silver catalyst chiral ligand.Name: (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole.
A highly enantioselective synthesis of homoallylic amines, using allyltrimethoxysilane under AgI catalytic conditions, has been developed. Among the chiral ligands investigated, a remarkable difference in the resulting AgI complexes was observed Under mild conditions and low catalyst loadings, homoallylamines were produced in high ee values (up to 80%) and good yields. The methodol. can be further extended to a diastereoselective and enantioselective crotylation of aldimines. © Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009.
