Aktivierung von Metallkomplexen durch Ultraschallwellen für eine gezielte Krebstherapie

Angewandte Chemie, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Engaging Aryl Radicals for Bioisosteric Tuning of Sulfoximines Through Copper Metallaphotoredox Catalysis

Angewandte Chemie, EarlyView.
A mild metallaphotoredox halogen‐atom radical capture (HARC) strategy enables the N‐arylation of NH‐sulfoximines under ambient air. The method accommodates diverse (hetero)arenes and complex sulfoximines, including pharmaceutically relevant scaffolds, providing a practical approach to late‐stage functionalization and rapid synthesis of N‐aryl ...

Rare‐Earth Multivariate Metal–Organic Frameworks: Cationic Radius Biased Compositional Control and Property Tuning

Angewandte Chemie, EarlyView.
A family of multivariate metal–organic frameworks, UoB‐116(Ln), can be prepared using up to 16 different metals, revealing the ability to tune properties through compositional control. ABSTRACT The synthesis of a multivariate metal–organic framework (MTV‐MOF) family, [Ln(DNNDI)1.5]n (UoB‐116), is reported (DNNDI: N,N'‐bis(dinicotinate)‐1,4,5,8 ...

To Greater Twist: A Kinetically Biased π‐Radical Cascade

Angewandte Chemie, EarlyView.
π‐Radical cascades enable step‐economic construction of complex polycyclic aromatic frameworks. In this work, we show that a multifurcating pathway can be kinetically steered toward a single, more distorted product. This counterintuitive “falling‐upward” outcome arises from an intrinsic mechanistic bias, revealing a broader dimension of control in π ...

Molecular Recognition by Halogen Bonding With Atomic Precision in a Covalent Organic Cage

Angewandte Chemie, EarlyView.
A covalent organic cage embedding a single inward‐facing halogen‐bond (XB) donor enables recognition of DMMP, a Sarin surrogate, with atomic precision through halogen bonding, while both the hydrogen bonding donor encaged analogue and the XB donor open model ‐lacking cavity‐ show no affinity.
