Full Control of the Chiral Overpass Effect in Helical Polymers: P/M Screw Sense Induction by Remote Chiral Centers After Bypassing the First Chiral Residue
نویسندگان
چکیده
In helical polymers, sense induction is usually commanded by teleinduction mechanism, where the largest substituent of chiral residue directly attached to main chain one that commands sense. this work, different structures with senses are induced in a polymer [poly-(phenylacetylene)] when conformational composition two dihedral angles pendant group more than residues tamed. Thus, while angle at 1 [(R)- or (S)-alanine], backbone, produces an extended bent conformation resulting scaffolds stretching degree, second 2 (S)-methoxyphenylacetamide] places substituents center spatial orientation, originating opposite through total control “chiral overpass effect”.

Review High-performance liquid chromatographic enantioseparation of drugs containing multiple chiral centers on chiral stationary phases
In recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. High-performance liquid Chromatography is a very useful method for the direct separation of enantiomers. However, about 30−40 years ago, commercially available chiral stationary phases wer...
متن کاملChiral molecule adsorption on helical polymers.
We present a lattice model for helicity induction on an optically inactive polymer due to the adsorption of exogenous chiral amine molecules. The system is mapped onto a one-dimensional Ising model characterized by an on-site polymer helicity variable and an amine occupancy one. The equilibrium properties are analyzed in the limits of strong coupling between helicity induction and amine adsorpt...
متن کاملChiral recognition mechanisms of four β-blockers by HPLC with Amylose Chiral Stationary Phase
The high performance liquid chromatography (HPLC) enantioseparation of four β-blocking agents metoprolol, bisoprolol, propranolol and atenolol was performed on amylose tris-(3,5-dimethylphenylcarbamate) chiral stationary phase using n-hexane-ethanol-diethylamine (DEA) as the mobile phase and related chiral recognition mechanisms were discussed. Enantiomeric separation of the fourβ-blockers was ...
