Controlling the Guanidinium Cation Rotation by Cation–π Interactions

Angewandte Chemie International Edition, EarlyView.
A lanthanide π‐container has been employed to trap a guanidinium cation inside the aromatic cavity by cation–π interactions. X‐ray crystallography and solid‐state nuclear magnetic resonance (NMR) spectroscopy at fast magic‐angle spinning (MAS) frequencies have been utilized to probe the underlying host–guest interactions.

Asymmetric α‐Alkylation With Activated and Unactivated Electrophiles by a Highly Productive and Recyclable Lewis Acid/Imidazolium Catalyst

Angewandte Chemie International Edition, EarlyView.
An air‐stable, easily prepared, bifunctional Cu(II)/imidazolium complex enables highly enantioselective α‐alkylation of 1,3‐dicarbonyls with outstanding productivity (TON up to 1740). Highlights include broad electrophile scope spanning π‐activated and nonactivated reagents, stereo‐retentive allylation, simple catalyst synthesis, and efficient catalyst

Engineering Murine Cross‐Reactivity Into an Affibody to Human Death Receptor 5

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Interspecies cross‐reactive protein therapeutics that target conserved epitopes across species are critical for translational research. The present study showcases the engineering of an affibody molecule, originally discovered for binding to human death receptor 5 (hDR5) with 94 nM affinity, to simultaneously acquire cross‐reactivity to murine
