The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine( cas:1265884-98-7 ) is researched.Recommanded Product: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine.Qiao, Jianhui; Chang, Wenju; Zhao, Wenxuan; Liang, Yong; Wang, Shaozhong published the article 《Kinetic Resolution of Spiroindolines through Ir-Catalyzed Asymmetric Allylative Ring-Opening Reaction》 about this compound( cas:1265884-98-7 ) in Organic Letters. Keywords: indole annulated medium sized lactam asym preparation; racemic spiroindoline kinetic resolution allylative ring opening iridium catalyst. Let’s learn more about this compound (cas:1265884-98-7).
Kinetic resolution of racemic spiroindolines I [R = H, Me, MeO, F, Cl; X = H, Me, Cl; Y = H, Me, MeO, F, Cl; Z = H, Me, MeO, F; no stereo] with s factors of ≤15200 was developed to access enantiomerically enriched indole-annulated medium-sized lactams II [R1 = Ph, 2-thienyl, 2-naphthyl, etc.] and spiroindolines I [stereo = R] through Ir-catalyzed asym. allylative ring-opening reaction. D. functional theory calculations supported the idea that the accurate discrimination of two spiroindoline enantiomers by (η3-allyl)-iridium(III) species and the perfect central-to-axial chirality conversion during C-C bond fragmentation ensure the stereoselective formation of two contiguous stereogenic centers and one axis in the medium-sized lactams.
