Preparation of Resolved Fourfold Symmetric Amphiphilic Helices Using Chiral Metallacrown Building Blocks
The chirality of the ligand determines the nature of the helix: Coordination of a chain of [15]metallacrown‐5 complexes based on phenylalanine hydroxamic acid results in an amphiphilic metallohelix with a 41 screw axis. The use of the L isomer of the acid gives the right‐handed helix (see left struc...

Zusammenfassung: | The chirality of the ligand determines the nature of the helix: Coordination of a chain of [15]metallacrown‐5 complexes based on phenylalanine hydroxamic acid results in an amphiphilic metallohelix with a 41 screw axis. The use of the L isomer of the acid gives the right‐handed helix (see left structure) while the D isomer gives the mirror image structure. |
