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 Synergetic iridium and amine catalysis enables asymmetric [4+2] cycloadditions of vinyl aminoalcohols with carbonyls, published in 2019-12-31, which mentions a compound: 1265884-98-7, mainly applied to dihydroquinolinone preparation enantioselective; vinyl aminoalc aldehyde cycloaddition iridium amine catalysis, Formula: C34H22NO2P.
Catalytic asym. cycloadditions via transition-metal-containing dipolar intermediates are a powerful tool for synthesizing chiral heterocycles. However, within the field of palladium catalysis, compared with the well-developed normal electron-demand cycloadditions with electrophilic dipolarophiles, a general strategy for inverse electron-demand ones with nucleophilic dipolarophiles remains elusive, due to the inherent linear selectivity in the key palladium-catalyzed intermol. allylations. Herein, based on the switched regioselectivity of iridium-catalyzed allylations, two asym. [4+2] cycloadditions of vinyl aminoalcs. with aldehydes and β,γ-unsaturated ketones through synergetic iridium and amine catalysis were achieved. The activation of vinyl aminoalcs. by iridium catalysts and carbonyls by amine catalysts provide a foundation for the subsequent asym. [4+2] cycloadditions of the resulting iridium-containing 1,4-dipoles and (di)enamine dipolarophiles. The former provides a straightforward route to a diverse set of enantio-enriched hydroquinolines bearing chiral quaternary stereocenters, and the later represent an enantio- and diastereodivergent synthesis of chiral hydroquinolines.
I hope my short article helps more people learn about this compound(5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine)Formula: C34H22NO2P. Apart from the compound(1265884-98-7), you can read my other articles to know other related compounds.
