The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine(SMILESS: N1(P2OC3=CC=C4C=CC=CC4=C3C5=C6C=CC=CC6=CC=C5O2)C7=CC=CC=C7C=CC8=CC=CC=C81,cas:1265884-98-7) is researched.Recommanded Product: 8-Hydroxyquinoline 1-oxide. The article 《Allenylic Carbonates in Enantioselective Iridium-Catalyzed Alkylations》 in relation to this compound, is published in Journal of the American Chemical Society. Let’s take a look at the latest research on this compound (cas:1265884-98-7).
An enantioconvergent C(sp3)-C(sp3) coupling between racemic allenylic electrophiles and alkylzinc reagents has been developed. An Ir/(phosphoramidite,olefin) catalyst provides access to highly enantioenriched allenylic substitution products (93-99% ee) with complete regiocontrol (>50:1 rr in all cases) over the undesired 1,3-dienes isomers which are obtained predominantly in the case of other metal catalysts. The synthetic utility of the products obtained was highlighted in a variety of stereoselective transition metal-catalyzed difunctionalization reactions. Furthermore, a combination of computational and exptl. studies supports a putative reaction mechanism wherein enantiodetermining C-C coupling occurs via nucleophilic attack on a highly planarized aryl butadienyl π-system that is coordinated to the Ir center in an η2-fashion.
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)Formula: C34H22NO2P, and with the development of science, more effects of this compound(1265884-98-7) can be discovered.
