In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Asymmetric γ-Allylation of α,β-Unsaturated Aldehydes by Combined Organocatalysis and Transition-Metal Catalysis, published in 2015, which mentions a compound: 1265884-98-7, mainly applied to aldehyde unsaturated regioselective enantioselective diastereoselective allylation allylic alc acetate; cyclic aldehyde dienoic asym synthesis; allylation; asymmetric catalysis; diastereodivergence; dual catalysis; regiodivergence, Application of 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.
Although many compounds look similar to this compound(1265884-98-7)Application of 1265884-98-7, numerous studies have shown that this compound(SMILES:N1(P2OC3=CC=C4C=CC=CC4=C3C5=C6C=CC=CC6=CC=C5O2)C7=CC=CC=C7C=CC8=CC=CC=C81), has unique advantages.
