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.
As far as I know, this compound(1214711-48-4)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 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
