Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. 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 Asymmetric NHC-catalyzed synthesis of α-fluoroamides from readily accessible α-fluoroenals.HPLC of Formula: 1214711-48-4.
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.
There is still a lot of research devoted to this compound(SMILES：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)HPLC of Formula: 1214711-48-4, and with the development of science, more effects of this compound(1214711-48-4) can be discovered.
