Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Organic Letters called Palladium Catalyzed Cyclizations of Oxime Esters with 1,2-Disubstituted Alkenes: Synthesis of Dihydropyrroles, Author is Race, Nicholas J.; Bower, John F., which mentions a compound: 175136-62-6, SMILESS is FC(C1=CC(C(F)(F)F)=CC(P(C2=CC(C(F)(F)F)=CC(C(F)(F)F)=C2)C3=CC(C(F)(F)F)=CC(C(F)(F)F)=C3)=C1)(F)F, Molecular C24H9F18P, Recommanded Product: Tris(3,5-bis(trifluoromethyl)phenyl)phosphine.
Pd-catalyzed cyclizations of oxime esters with 1,2-dialkylated alkenes provide an entry to chiral dihydropyrroles. Substrate and catalyst controlled strategies for selective product formation (vs. alternative pyrroles) are outlined.
Although many compounds look similar to this compound(175136-62-6)Recommanded Product: Tris(3,5-bis(trifluoromethyl)phenyl)phosphine, numerous studies have shown that this compound(SMILES:FC(C1=CC(C(F)(F)F)=CC(P(C2=CC(C(F)(F)F)=CC(C(F)(F)F)=C2)C3=CC(C(F)(F)F)=CC(C(F)(F)F)=C3)=C1)(F)F), has unique advantages.
