A new series of sulfonylcycloureas derivatives have been synthesized and evaluated in vitro for their antitumor activity against four cancer cell lines (A431, Jurkat, U266, and K562). These compounds were prepared by the condensation of several sulfonamides (2a–m) with ethyl bis(2-chloroethyl)carbamate (1a). The relative cytotoxicity of these new derivatives in comparison to chlorambucil is reported

Sulfamates and sulfamides are most often synthesized from alcohols and amines with sulfamoylchloride, 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 reaction is hexafluoroisopropanol (HFIP) and reaction
An eco-friendly, simple, mild, chemo selective and highly efficient procedure for the acylation of primary and secondary amine function in various structurally and electronically aliphatic and aromatic compounds affording their corresponding N-Ac derivatives is developed. Mild conditions, simplicity and easier work-up are the main advantages of this method.

Abstract Mono- and bis-N-sulfamoylamidines have been efficiently synthesized by the direct condensation of sulfamides and amides in the presence of phosphorus oxychloride via electrophilic activation. The scope of this reaction is discussed, and detailed synthetic studies show that the desired products are generated in high yields under mild conditions. Graphical Abstract
