Stereospecific Assembly of Triply Chiral Pseudopeptidic Cages Through Dynamic Dual Chirality Transfer

open access: yesAngewandte Chemie, Volume 138, Issue 11, 9 March 2026.
The spontaneous assembly of triply chiral (L, Δ, P or D, Λ, M) cages has been achieved from a simple tripodal chiral effector based on phenylalanine tris(amidoamine), non‐chiral bipyridine dialdehyde, and a metal ion. Orthogonal imine bond and iron (II) coordination generate a single combination of chiral elements, while configurationally stable ...
