The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (S)-Butan-2-ol( cas:4221-99-2 ) is researched.Formula: C4H10O.Liu, Zexi; Ai, Jing; Kumar, Prashant; You, Enming; Zhou, Xiong; Liu, Xi; Tian, Zhongqun; Bour, Petr; Duan, Yingying; Han, Lu; Kotov, Nicholas A.; Ding, Songyuan; Che, Shunai published the article 《Enantiomeric Discrimination by Surface-Enhanced Raman Scattering-Chiral Anisotropy of Chiral Nanostructured Gold Films》 about this compound( cas:4221-99-2 ) in Angewandte Chemie, International Edition. Keywords: enantioseparation surface enhanced raman scattering chiral anisotropy gold film; chiral anisotropy; chiral nanostructured Au film; chiral response; enantiomeric discrimination; surface-enhanced Raman scattering. Let’s learn more about this compound (cas:4221-99-2).
A surface-enhanced Raman scattering-chiral anisotropy (SERS-ChA) effect is reported that combines chiral discrimination and surface Raman scattering enhancement on chiral nanostructured Au films (CNAFs) equipped in the normal Raman scattering Spectrometer. The CNAFs provided remarkably higher enhancement factors of Raman scattering (EFs) for particular enantiomers, and the SERS intensity was proportional to the enantiomeric excesses (ee) values. Except for mols. with mesomeric species, all of the tested enantiomers exhibited high SERS-ChA asymmetry factors (g), ranging between 1.34 and 1.99 regardless of polarities, sizes, chromophores, concentrations and ee. The effect might be attributed to selective resonance coupling between the induced elec. and magnetic dipoles associated with enantiomers and chiral plasmonic modes of CNAFs.
