Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1214711-48-4, is researched, SMILESS is ClC1=C(N2N=C3[N+]([C@@]4([H])[C@@](CC5=C4C=CC=C5)([H])OC3)=C2)C(Cl)=CC(Cl)=C1.F[B-](F)(F)F, Molecular C18H13BCl3F4N3OJournal, Advanced Synthesis & Catalysis called Asymmetric Synthesis of Dihydronaphthalene-1,4-diones via Carbene-Catalyzed Stereodivergent Reaction, Author is Zhao, Zhifei; Yang, Shuang; Lan, Shouang; Liu, Jinggong; Liu, Shuhua; Fang, Xinqiang, the main research direction is dihydronaphthalenedione enantioselective preparation; formylaryl diketone preparation enantioselective benzoin cyclization carbene catalyst.Quality Control of (5aS,10bR)-2-(2,4,6-Trichlorophenyl)-4,5a,6,10b-tetrahydro-2H-indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazin-11-ium tetrafluoroborate.
2-Hydroxy-2,3-dihydronaphthalene-1,4-diones (HDNDs) are ubiquitous in natural products and bioactive mols., but the rapid asym. construction of such scaffolds remains a significant challenge to date. Reported herein is the rapid construction of the above key units via carbene-catalyzed benzoin reaction. The resolution technique of divergent reaction on racemic mixture (divergent RRM) was employed, affording both isomers of HDNDs in a one-step fashion. Disubstituted substrates afford products with two contiguous quaternary stereocenters. A series of highly selective transformations on the products can be realized, and mechanistic studies indicate that the benzoin reaction is much faster than the racemization process and the aldol reaction.
