This literature about this compound(1787246-78-9)Recommanded Product: 1787246-78-9has given us a lot of inspiration, and I hope that the research on this compound((5aS,10bR)-2-(2,6-Diethylphenyl)-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 further advanced. Maybe we can get more compounds in a similar way.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Wang, Lei; Li, Sun; Bluemel, Marcus; Puttreddy, Rakesh; Peuronen, Anssi; Rissanen, Kari; Enders, Dieter researched the compound: (5aS,10bR)-2-(2,6-Diethylphenyl)-4,5a,6,10b-tetrahydro-2H-indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazin-11-ium tetrafluoroborate( cas:1787246-78-9 ).Recommanded Product: 1787246-78-9.They published the article 《Switchable Access to Different Spirocyclopentane Oxindoles by N-Heterocyclic Carbene Catalyzed Reactions of Isatin-Derived Enals and N-Sulfonyl Ketimines》 about this compound( cas:1787246-78-9 ) in Angewandte Chemie, International Edition. Keywords: spirocyclopentane oxindole preparation heterocycle carbene catalyst enal sulfonyl ketimine; N-heterocyclic carbenes; asymmetric synthesis; heterocylces; organocatalysis; spiro-compounds. We’ll tell you more about this compound (cas:1787246-78-9).

A novel NHC-catalyzed annulation protocol for the asym. synthesis of biol. important β-lactam fused spirocyclopentane oxindoles with four contiguous stereocenters, including two quaternary carbon centers, was developed. Alternatively, spirocyclopentane oxindoles containing an enaminone moiety can be achieved using the same starting materials, isatin-derived enals, and N-sulfonyl ketimines, in the presence of a slightly different NHC catalytic system. This switchable annulation strategy enables the selective assembly of both heterocyclic scaffolds with good yields and excellent enantioselectivities for a broad range of substrates.
