Formula: C18H13BCl3F4N3O. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: (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, is researched, Molecular C18H13BCl3F4N3O, CAS is 1214711-48-4, about N-Heterocyclic carbene-catalyzed desymmetrization of functionalized 1,4-dienes via Stetter Reaction. Author is Lin, Qiqiao; Li, Yuanzhen; Das, Deb Kumar; Zhang, Guoxiang; Zhao, Zhifei; Yang, Shuang; Fang, Xinqiang.
The asym. desymmetrization of 1,4-dienes via chiral N-heterocyclic carbene catalyzed Stetter-type umpolung reaction was demonstrated. A variety of differently substituted dienes were tolerated very well, affording cyclic ketones with two consecutive stereogenic centers (including one quaternary carbon) in moderate to high yields and with high to excellent enantioselectivities. This work expanded both reaction types of catalytic diene desymmetrizations and substrate diversity in NHC catalyzed desym. transformations.
