Since various helical supramol. polymers became available, their application to mol. chirality recognition have been anticipated but not extensively studied. So far, only a few examples of chiral reactions have been reported, but none for chiral separation Here, we report the application of a helical supramol. polymer to the enantio-separation of chiral guest mols. The monomer of this supramol. polymer is the salt-pair of a dendritic carboxylic acid with an enantiopure amino alc. In an apolar solvent, this salt-pair stacks via hydrogen bonds to form a helical polymer. In conjunction with this carboxylic acid, various amino alcs. afford supramol. polymers, whose helical handedness is determined by the stereochem. of the amino alcs. When two salts with the same chirality are mixed, they undergo copolymerization, while those with opposite chirality do not. Owing to this stereoselective copolymerizability, the helical supramol. polymer could bias the enantiomeric composition of chiral amino alcs. The experimental part of the paper was very detailed, including the reaction process of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7Computed Properties of C9H11NO)
(1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7) belongs to anime. The reaction of alkyl halides, R―X, where X is a halogen, or analogous reagents with ammonia (or amines) is useful with certain compounds. Not all alkyl halides are effective reagents; the reaction is sluggish with secondary alkyl groups and fails with tertiary ones. Its usefulness is largely confined to primary alkyl halides (those having two hydrogen atoms on the reacting site).Computed Properties of C9H11NO
