From Berzelius to Hyperspace: Previously Unrecognized Network of Reactivity in Textbook Brominations

Angewandte Chemie, EarlyView.
Robotic scans across multidimensional condition spaces of classic bromination reactions uncover regions of previously unrecognized reactivity, yielding new major products and novel substitution patterns. Correlation and anticorrelation analyses of product distributions across these hyperspaces enable reconstruction of the underlying mechanistic ...

Azole γ‐Peptides Helix Switching via Heterocycle Substitutions

Angewandte Chemie, EarlyView.
Heterocycle substitution in azole‐based γ‐amino acids enables control over the helical shape of heterocyclic γ‐peptides. S↔N permutation in thiazole residues switches a canonical 9‐helix into a flexible helix exhibiting discontinuous hydrogen bonding.

Adaptive Hydrogenation of Alkynes Using CO as a Molecular Trigger to Selectively Produce Alkanes or Z‐Alkenes

Angewandte Chemie, EarlyView.
One catalyst for two products: CO acts as a molecular trigger for adaptive alkyne hydrogenation using supported Pd nanoparticles. The catalyst reversibly switches between the formation of alkanes under H2 and Z‐alkenes under H2/CO for 37 structurally diverse alkynes.

Rapidly Diversifying Hydrogen‐Bonded Organic Frameworks With Permanent Porosity

Angewandte Chemie, EarlyView.
This article reviews diversifying hydrogen‐bonded organic frameworks (HOFs) with permanent porosity reported over the past 15 years, based on the molecular structures of their constituent tectons. Furthermore, several distinctive aspects and concepts are described, such as permanent porosity, isostructural (isoreticular) HOFs, and multicomponent mixed ...
