Hexafluoroisopropyl Sulfamate: A Useful Reagent for the Synthesis of Sulfamates and Sulfamides

Organic Letters, 2021
Sulfamates and sulfamides are most often synthesized from alcohols and amines with sulfamoyl chloride, which is an unstable reagent. We have identified hexafluoroisopropyl sulfamate (HFIPS) as a bench-stable solid that reacts readily with a wide variety of alcohols, amines, phenols, and anilines under mild reaction conditions. The sole byproduct of the

Sulfamate in environmental waters

Science of The Total Environment, 2019
Although sulfamate (the anion of sulfamic acid) has been in use for decades in various industrial and other applications, there is no previously published information about its occurrence and fate in environmental waters. In this study sulfamate was widely detected in environmental waters in Ontario, Canada, ranging up to 128,000ng/L.

Adenosine sulfamates: Next generation of antimalarials

Cell Host & Microbe, 2022
Tackling the ancient infectious foe of malaria, Xie et al. (2022) uncover a novel class of nucleoside analogs that selectively hijack and inhibit the tyrosine tRNA synthase of the parasite. With high potency, good oral bioavailability, and minimal host cell toxicity, these inhibitors show promise as next-generation antimalarials.

Therapeutic applications of sulfamates

Expert Opinion on Therapeutic Patents, 2004
Sulfamic acid, a rather simple molecule used widely by medicinal chemists for the design of a host of derivatives with pharmacological applications, may give rise to at least four types of derivatives, the O-substituted-, N-substituted- or di-/tri-substituted sulfamates, which also show specific biological activities.

Vibrational Spectra and Structure of Solid Sulfamic Acid and the Sulfamate Ion

The Journal of Chemical Physics, 1957
The infrared spectra of finely powdered samples in pressed disks of KBr have been obtained for sulfamic acid, sodium and potassium sulfamates, and the corresponding deutero-compounds in the region from 4000 to 500 cm—1 at several temperatures. Satisfactory vibrational assignments could be made for the zwitterion model of the acid, H3N+–SO3—, with site ...

Structure-activity studies on sulfamate sweeteners

Journal of Medicinal Chemistry, 1976
The structure-activity relationships governing sulfamate sweeteners are reviewed under the headings: size of the reduced ring, changes in the sulfamate function, substitution of hydrogen in the ring, and substitution of carbon in the ring and open-chain compounds.

Solid-Phase Synthesis of Sulfamate Peptidomimetics

Journal of Combinatorial Chemistry, 2007
A synthetic method for the preparation of sulfamate peptidomimetics is described. The methodology allows sulfamoylation in the solid phase using sulfamoyl chloride in DMA, followed by the acylation of the corresponding sulfamoylated product. Following this approach, several derivatives have been prepared starting from distinct alcohol sources ...
