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 Divergent Dynamic Kinetic Resolution of a Racemic Mixture of Four Stereoisomers via N-Heterocyclic Carbene Organocatalysis, published in 2018, which mentions a compound: 1214711-48-4, mainly applied to divergent dynamics kinetics racemic stereoisomer heterocyclic carbene organocatalyst; benzoin; divergent dynamic kinetic resolution; organocatalysis; stereocenters; stereoisomers; tetralone, Name: (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.
Racemic mixtures of four stereoisomers are easily formed via many fundamental organic transformations, but the direct utilities of these mixtures were less studied and remain large challenges to date. The authors introduce a new method, i.e., divergent dynamic kinetic resolution, to achieve the separation of racemic mixtures of four stereoisomers. The hypothesis was proved by using a N-heterocyclic carbene-catalyzed benzoin reaction, which afforded two separable diastereomeric products bearing three consecutive stereocenters with good to excellent enantioselectivities. The authors believe that this resolution protocol will find applications in more transformations.
The article 《Divergent Dynamic Kinetic Resolution of a Racemic Mixture of Four Stereoisomers via N-Heterocyclic Carbene Organocatalysis》 also mentions many details about this compound(1214711-48-4)Name: (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, you can pay attention to it, because details determine success or failure
