Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1214711-48-4, is researched, SMILESS is ClC1=C(N2N=C3[N+]([C@@]4([H])[C@@](CC5=C4C=CC=C5)([H])OC3)=C2)C(Cl)=CC(Cl)=C1.F[B-](F)(F)F, Molecular C18H13BCl3F4N3OJournal, Article, Chemical Science called Asymmetric NHC-catalyzed synthesis of α-fluoroamides from readily accessible α-fluoroenals, Author is Wheeler, Philip; Vora, Harit U.; Rovis, Tomislav, the main research direction is enantioselective alpha fluoroamide preparation unsaturated aldehyde amine hydrochloride; diastereoselective alpha fluoroamide synthesis enantioenriched amine alpha fluoroenal reactant; nitrogen heterocyclic carbene catalyst redox amidation alpha fluoroamide preparation; amide functionalization amine fluorohydrin preparation enantioenrichment retention.Recommanded Product: (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.
The scope of the NHC-redox amidation has been expanded to include a variety of α,β-unsaturated aldehydes, including α-fluoro α,β-unsaturated aldehydes, which give rise to enantioenriched α-fluoroamides in good to excellent yield and enantioselectivity (up to 97% ee). Enantioenriched amines may be elaborated to either diastereomer of the product in high diastereoselectivity (up to 99 : 1). Functionalization of the amide products to amines and fluorohydrins is also demonstrated with retention of enantioenrichment at the fluorine stereocenter.
From this literature《Asymmetric NHC-catalyzed synthesis of α-fluoroamides from readily accessible α-fluoroenals》,we know some information about this compound(1214711-48-4)Recommanded Product: (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, but this is not all information, there are many literatures related to this compound(1214711-48-4).
