Efficient Synthesis of Sulfonyl Azides from Sulfonamides

open access: yes, 2016
Triflyl azide serves as an efficient diazo transfer reagent in this first direct synthesis of sulfonyl azides from readily available and stable sulfonamides. The process is experimentally simple, mild, and high-yielding.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

open access: yesAdvanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Catalytic Racemization of Activated Organic Azides

open access: yes, 2018
The first detailed description of the catalytic racemization of activated benzylic and allylic azides under mild conditions is reported. A kinetic analysis of the observed racemization indicates a first-order dependence on azide, a first-order dependence

Friend, Not Foe: Lowered Tissue Reactivity to Long‐Term Polyimide Implants

open access: yesAdvanced Science, EarlyView.
The choice of optimal neural probe designs remains a major challenge in the field of neurotechnology. This study investigated the biocompatibility of several probe variations, including material, thickness, width, and implantation strategy. It highlights the clear advantage of soft polyimide probes over stiff silicon probes for better device ...

Conversion of Alkyl Azides to Diazo Compounds and the Azide-Site Selectivity: One-Pot Phosphine-Mediated Transient Protection of Azido Groups and Deprotective Transformation to Diazo Groups [PDF]

open access: yes
A one-pot conversion of alkyl azides to diazo compounds is outlined. After azido group protection of α-azidocarbonyl compounds, treatment of the resulting phosphazides with silica gel in a wet solvent afforded α-diazo carbonyl products by azide ...

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

open access: yesAdvanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Boryl Azides in 1,3-Dipolar Cycloadditions

open access: yes, 2016
The 1,3-dipolar cycloaddition reaction of boron azides with alkynes has been investigated experimentally and computationally. At room temperature pinBN3 (pin = pinacolato) reacts with the strained triple bond of cyclooctyne with formation of an ...
