Recommanded Product: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine, is researched, Molecular C36H30NO2P, CAS is 415918-91-1, about Iridium-Catalyzed Enantioselective Allylic Substitution of Aliphatic Esters with Silyl Ketene Acetals as the Ester Enolates. Author is Jiang, Xingyu; Hartwig, John F..
An iridium-catalyzed enantioselective allylic substitution of aliphatic esters (E)-R1CH:CHCH2OC(O)Ph (R1 = Ph, 4-MeC6H4, 2-thienyl, 3-pyridyl, etc.) with silyl ketene acetals R22C:C(OR3)SiMe3 [R2 = Me, Et; R22 = (CH2)3, (CH2)5, (CH2)2O(CH2)2, etc.; R3 = Me, i-Pr, t-Bu, Ph, etc.] to form products containing a quaternary carbon atom at the nucleophile moiety and a tertiary carbon atom at the electrophile moiety is reported. Under relatively neutral conditions, the allylated aliphatic esters H2C:CHCH(R1)CR22CO2R3 were obtained with excellent regio- and enantioselectivity. These products were readily converted into primary alcs., carboxylic acids, amides, isocyanates, and carbamates, as well as THF and γ-butyrolactone derivatives, without erosion of enantiomeric purity.
