1,3‐Brook Rearrangement of α‐Silyl Allylic Alcohols: Copper‐Catalyzed Enantiospecific Formation of Allenes and Copper‐Mediated ipso‐Substitution Reactions Affording Trisubstituted Alkenes

Angewandte Chemie, EarlyView.
A regioselective ruthenium catalyzed trans‐hydrosilylation of propargyl alcohols followed by a 1,3‐Brook rearrangement opens access to reactive organocopper intermediates, which evolve upon warming into allenes with strict chirality transfer to the emerging axis; alternatively, these reactive species can be trapped with a large variety of electrophiles

Organic Electrochemical Transistors for Energy‐Autonomous Bioelectronics: Materials, Devices, and System Integration

Advanced Electronic Materials, EarlyView.
This review surveys organic electrochemical transistors as core building blocks for energy‐autonomous bio‐integrated electronics. We outline device physics, OMIEC materials, and electrolyte effects that enable sub‐volt, high‐gain operation, and discuss direct coupling with mechanical, thermal, and optical energy harvesters to realize battery‐free ...

Deprotonation and Alkylation of Weakly Acidic C(sp3)─H Bonds Through In Situ Generation of a Strong Hydride Base From 1,1,3,3‐Tetramethyldisiloxane and Potassium tert‐Butoxide

Angewandte Chemie, EarlyView.
The use of 1,1,3,3‐tetramethyldisiloxane (TMDSO) and potassium tert‐butoxide enables direct alkylation of weakly acidic carbon–hydrogen bonds with alkyl halides. Experimental and computational studies support the formation of a substrate‐associated hydride‐like base, providing a single‐step alternative to the classical deprotonation and electrophile ...

How small changes to methylated piperidinium cations impact the synthesis of zeolite SSZ‐39

AIChE Journal, EarlyView.
Abstract Here we report a synthesis study of SSZ‐39 with four different organic structure directing agents (OSDA). The goal was to determine how subtle changes to the OSDA architecture impact crystallization kinetics, material composition, and other properties.

1,4‐Brook Rearrangement of β‐Silyl Allylic Alcohols: Trisubstituted Alkenes by Copper‐Mediated Stereoretentive ipso‐Substitution Reactions

Angewandte Chemie, EarlyView.
To fully leverage the power of the ruthenium‐catalyzed trans‐hydrosilylation of propargyl alcohols, it was necessary to develop a practical and robust method for the activation of those products that carry the silyl group distal to the hydroxy substituent.

Distribution of Big Tau Isoforms in the Human Central and Peripheral Nervous System

Annals of Neurology, EarlyView.
Objective Tau is widely studied in neurodegeneration, yet most work has focused on canonical brain tau isoforms. A longer isoform, “big tau,” produced by inclusion of exon 4a, is expressed in the peripheral nervous system (PNS) and central nervous system (CNS) regions.

Supramolecular Polymer‐Surfactant Co‐Assemblies for Multivalent HSV‐1 Inhibition

Angewandte Chemie, EarlyView.
Non‐covalent co‐assembly of BTA with antiviral surfactants produces ratio‐dependent morphologies. Fibrous supramolecular polymers exhibit superior HSV‐1 inhibition, revealing multivalent fiber‐virus interactions and highlighting supramolecular co‐assemblies as a powerful strategy for functional biomedical nanomaterials with demonstrated tunable ...
