Chiral Microenvironments in Self-Assembled Capsules
نویسنده
چکیده
A nonracemic compound is synthesized and shown to assemble reversibly through hydrogen bonding to form a cyclic tetramer. The chiral arrangement of atoms in the individual pieces becomes amplified through self-assembly to yield multiple functional groups asymmetrically arranged within the cavity. The tetrameric capsule shows a special affinity for ketones and is able to discriminate between their enantiomers in solution.

A self-assembled chiral capsule with polar interior.
Phenylalanine substituted resorcinarenes form self-complementary dimeric homo- or heterochiral capsules based on deeply buried electrostatic interactions (salt bridges) with numerous polar and non-polar functionalities in their interiors available for interactions with encapsulated polar molecules, as proved by X-ray analysis and diffusion NMR spectroscopy.
متن کاملHighly diastereoselective self-assembly of chiral tris(m-ureidobenzyl)amino capsules.
The self-assembly of chiral tris(m-ureidobenzyl)amines to give dimeric capsules is a highly diastereoselective process in solution, while in the solid state, the formation of the corresponding capsules is not only diastereoselective but also regioselective.
متن کاملReversible switching between self-assembled homomeric and hybrid capsules.
We present here the reversible, guest-controlled disproportionation of homomeric and hybrid capsules using photochemistry. The supramolecular containers are self-assembled from shallow and deep cavitand modules.

Molecular capsules composed of amino acid or peptide derivatives connected to resorcin[4]arene scaffolds through acylhydrazone linkers have been synthesized using dynamic covalent chemistry (DCC) and hydrogen-bond-based self-assembly. The dynamic character of the linkers and the preference of the peptides towards self-assembly into β-barrel-type motifs lead to the spontaneous amplification of f...
متن کاملVersatile self-assembled molecular capsule formation of a resorcin[4]arene-based benzamidoiminocavitand.
The facile synthesis of a resorcin[4]arene-based imino-cavitand with benzamido moieties and its self-assembly into molecular capsules are reported. Benzamido-iminocavitand efficiently self-assembled into thermally inert molecular capsules in the presence of suitable guests via the eight intermolecular N-H···O=C hydrogen bonds.
