The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine, is researched, Molecular C34H22NO2P, CAS is 1265884-98-7, about Asymmetric γ-Allylation of α,β-Unsaturated Aldehydes by Combined Organocatalysis and Transition-Metal Catalysis, the main research direction is aldehyde unsaturated regioselective enantioselective diastereoselective allylation allylic alc acetate; cyclic aldehyde dienoic asym synthesis; allylation; asymmetric catalysis; diastereodivergence; dual catalysis; regiodivergence.Recommanded Product: 1265884-98-7.
The first asym. regio- and diastereodivergent γ-allylation of cyclic α,β-unsaturated aldehydes I (X = CH2, R1 = H, 7-F, 6-MeO, 5,7-Me2, etc.; X = O, S, R1 = H) with various allylic alcs. R2CH(OH)CH:CH2 (R2 = Ph, 2-MeC6H4, 4-MeOC6H4, 4-O2NC6H4, etc.) or allylic acetates R2CH:CHCH2OAc based on combined organocatalysis and transition-metal catalysis is disclosed. By combining an aminocatalyst with an iridium catalyst, both diastereomers of branched allylated products II can be obtained from I and allylic alcs. in moderate to good yields and excellent regio- and stereoselectivities. Furthermore, by replacing the iridium catalyst with a palladium catalyst, the linear allylated products III were formed in good yields and excellent regio- and enantioselectivities from I and allylic acetates. The developed method thus provides selective access to all six isomers of the γ-allylated product in a divergent fashion by choosing the appropriate combination of organocatalyst, transition-metal catalyst, and ligand.
