Synthesis of N-Substituted Sulfamate Esters from Sulfamic Acid Salts by Activation with Triphenylphosphine Ditriflate [PDF]
Organic Letters, 2017 A general approach to access sulfamate esters through preparation of sulfamic acid salts, subsequent activation with triphenylphosphine ditriflate, and nucleophilic trapping is disclosed. The method proceeds in modest to excellent yields to incorporate nucleophiles derived from aliphatic alcohols and phenols.

Self‐Healing Materials from Electronically Integrated Microscopic Robots
Advanced Intelligent Systems, Volume 8, Issue 1, January 2026.Submillimeter robots can use electronically controlled electrodeposition to assemble into a material structure. The resulting aggregate possesses ultralow density, high strength‐to‐weight ratio, and can heal from damage. Further afield, these results clear a path to materials that organize or adapt by directing matter and information at the microscale.

Decoding Urease Inhibition: A Comprehensive Review of Inhibitor Scaffolds
ChemMedChem, Volume 21, Issue 2, January 2026.Representative functional groups known for urease inhibition are reviewed within diverse scaffolds using structure–activity analyses to identify features associated with high inhibitory activity. Urease is a metalloenzyme produced by a wide range of organisms and plays a critical role in nitrogen microbial metabolism by catalyzing the hydrolysis of ...

Advanced Science, Volume 12, Issue 47, December 18, 2025.Insufficient hole injection in the quantum dot emission layer is the primary challenge limiting the performance of blue devices. Herein, a bilateral ligands modification strategy is proposed to enhance the hole injection efficiency on the basis of improving the hole transport efficiency, effectively improves the carrier recombination efficiency, with ...

Sulfatases: Catalytic Mechanism, Substrate Preferences, and Carbohydrate‐Based Inhibitor Design
Israel Journal of Chemistry, Volume 65, Issue 12, December 2025.Sulfatases are a class of enzymes that can cleave sulfates from heparan sulfate and modulate many of their biological activities. In this review, following a general introduction on sulfatase, their enzymatic mechanism and substrate scope are discussed.

Oxidative Cyclization of Sulfamates onto Pendant Alkenes
Organic Letters, 2020 This communication discloses the first examples of aza-Wacker cyclizations of sulfamate esters. Within the realm of related cyclization reactions, this protocol is differential in that it forms six-membered rings in good yield and uses catalytic amounts of palladium(0) rather than palladium(II) salts.
