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, Journal of the American Chemical Society called Construction of Vicinal Quaternary Centers via Iridium-Catalyzed Asymmetric Allenylic Alkylation of Racemic Tertiary Alcohols, Author is Isomura, Mayuko; Petrone, David A.; Carreira, Erick M., which mentions a compound: 1265884-98-7, SMILESS is N1(P2OC3=CC=C4C=CC=CC4=C3C5=C6C=CC=CC6=CC=C5O2)C7=CC=CC=C7C=CC8=CC=CC=C81, Molecular C34H22NO2P, Name: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine.
Enantioselective bond formation between sterically hindered fragments to furnish acyclic products with vicinal quaternary centers is a formidable challenge. We report a solution that involves cocatalysis between a chiral Ir-(phosphoramidite, olefin) complex and La(OTf)3. This robust catalytic system effects highly enantioconvergent and regioselective alkylation of racemic tertiary α-allenyl alcs. with tetrasubstituted silyl ketene acetals. The transformation displays broad functional group tolerance for both reaction components and allows efficient generation of β-allenyl ester products in good yield and with excellent enantioselectivity. Furthermore, both the allene and ester functionalities were leveraged to upgrade the structural complexity of the products via a series of stereoselective metal-catalyzed functionalization reactions.
There is still a lot of research devoted to this compound(SMILES：N1(P2OC3=CC=C4C=CC=CC4=C3C5=C6C=CC=CC6=CC=C5O2)C7=CC=CC=C7C=CC8=CC=CC=C81)Name: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine, and with the development of science, more effects of this compound(1265884-98-7) can be discovered.
