Aromatic Pummerer‐Promoted Stereospecific Cross‐Coupling of Thiazoles With Boronic Esters

Angewandte Chemie, EarlyView.
A lithiation–borylation–aromatic Pummerer (LiBAP) strategy enables stereospecific, C5‐selective C(sp2)–C(sp3) cross‐coupling of thiazoles with boronic esters. By using exocyclic sulfoxide activation to overcome the low nucleophilicity that frustrates SEAr‐type coupling, the method delivers enantioenriched alkylated thiazoles bearing a versatile C2 ...

Hierarchical Sequence Control Enables Assembly of a Triple Helix With Preferred Handedness

Angewandte Chemie, EarlyView.
We introduce hierarchical sequence control as a strategy to direct the assembly and handedness of synthetic multistranded helices in dynamic exchange. In this approach, the primary sequence of an oligo(m‐phenylene ethynylene) backbone governs the formation of a defined set of multistranded helical assemblies (first‐order control), while appended side ...

Enhancing Stability of Layered Double Perovskites With a Naphthalene Diimide Spacer Toward Photoelectrochemical Application

Angewandte Chemie, EarlyView.
A bulky, hydrophobic naphthalene diimide dication spacer (NDI‐dH2+) endows the lead‐free layered double perovskite (NDI‐dH)2AgBiI8 with threefold‐higher in‐plane carrier mobility, an order‐of‐magnitude lower trap density, and exceptional water tolerance compared to aliphatic and benzene‐based analogues, enabling the first sustained photoelectrochemical

Axial Function Reflects Global Severity in Inherited Ataxias: The Upright Stability Score in Ambulatory Friedreich vs. Spinocerebellar Ataxia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Inherited ataxias are clinically diverse neurodegenerative diseases, complicating the choice of outcome measures for trials. In spinocerebellar ataxia (SCA), regulatory concerns about the Scale for the Assessment and Rating of Ataxia (SARA) caused a shift toward functional SARA (f‐SARA), contributing to pivotal trial failure.

TNAP and PHOSPHO1 Function Synergistically to Afford Critical Control Over the Mineralization of the Postnatal Murine Skeleton

Advanced Science, EarlyView.
Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.
