Wu, Zijun; Wang, Xu; Li, Fangyi; Wu, Jicheng; Wang, Jian published the article 《Chemoselective N-Heterocyclic Carbene-Catalyzed Cascade of Enals with Nitroalkenes》. Keywords: dihydrocoumarin preparation chemoselective enantioselective cascade reaction enal nitroalkene; nitrogen heterocyclic carbene catalyzed cascade reaction enolate intermediate.They 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 ).Quality Control of (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. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1787246-78-9) here.
An unprecedented N-heterocyclic carbene catalyzed chemoselective and enantioselective cascade reaction of enals with nitroalkenes has been developed. A wide range of enantioenriched dihydrocoumarins has been prepared, and the reaction goes through an enolate intermediate generated under a catalytic process.
Compounds in my other articles are similar to this one((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)Quality Control of (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, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
