چکیده
SO2 gas is effectively used for the preparation of N,N'-diarylsulfamides and shape-persistent sulfamide polymers, which utilize a network of intermolecular N-H...O=S hydrogen bonds to self-assemble into soft porous materials.

Bacterial cleavage of nitrogen to sulfone bonds in sulfamide and 1H-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide : formation of 2-nitrobenzamide by Gordonia sp
Pure cultures of aerobic bacteria were isolated which could utilize sulfamate, sulfamide or 1H-2,1,3-benzothiadiazin-4(3H)one 2,2-dioxide (BTDD) as sole source of sulfur for growth and thus cleave a N^S(O)x bond. The molar growth yields indicated that each source of sulfur was utilized quantitatively. This was confirmed directly for Gordonia sp. strain BT2 utilizing BTDD, which was converted qu...
متن کاملSynthesis of New Fused Benzothiadiazepines and Macrocyclic Sulfamides Starting from N,N-Disubstituted Sulfamides and N(Boc)-Sulfamides
Herein, we describe an efficient one-step synthesis of new fused benzothiadiazepine-1,1-dioxides and macrocyclic sulfamides. The synthesis of these compounds was achieved in moderate yields starting from previously described N,N'-disubstituted symmetric sulfamides and N-tert-butoxycarbonyl, N'-alkyl sulfamide. The chemical structures of all the new compounds reported in this work were confirmed...
متن کاملModular Synthesis of 1,2-Diamine Derivatives via Palladium-Catalyzed Aerobic Oxidative Cyclization of Allylic Sulfamides.
Allylic sulfamides undergo efficient aerobic oxidative cyclization at room temperature, mediated by a new Pd catalyst system consisting of 5% Pd(TFA)(2)/10% DMSO in THF. The synthetic utility of these reactions is enhanced by several features: (1) the sulfamide substrates are accessible in multi-gram scale from the corresponding allylic and primary amines, (2) the cyclic sulfamide products are ...
متن کاملSynthesis and anti-mycobacterial activity of glycosyl sulfamides of arabinofuranose.
A series of arabino N-glycosyl sulfamides, forced to adopt the furanose form by removal of the 5-hydroxyl group, were synthesised as putative isosteric mimics of decaprenolphosphoarabinose, the donor processed by arabinosyltransferases during mycobacterial cell wall assembly. Compounds showed moderate anti-mycobacterial activity, which was maximal for a C10 sulfamide side chain.
متن کاملGlycoluril ribbons tethered by complementary hydrogen bonds.
Four complementary hydrogen bonds between sulfamides and ureas link adjacent hydrogen-bonded ribbons to form sheets in the solid-state; this interaction is investigated in solution using model urea and sulfamide compounds.
