Abstract:

Rate constants for the reaction between a secondary alkyl radical and two different sulfonyl azides were determined using bimolecular competing radical reactions. The rates of azidation were determined by competition with hydrogen atom transfer from tris(trimethylsilyl)silane ((TMS)3SiH) of the 4-phenylcyclohexyl radical. 3-Pyridinesulfonyl azide and trifluoromethanesulfonyl azide were found to have rate constants for azidation of 2 × 105 M–1 s–1 and 7 × 105 M–1 s–1 at 80°C, respectively.

Abstract:

2-Chloro-4-sulfonylquinazolines undergo functional group swap when treated with an azide nucleophile: 1) the azide replaces the sulfonyl group at the C4 position; 2) the intrinsic azide–tetrazole tautomeric equilibrium directs the nucleofugal sulfinate from the first step to replace chloride at the C2 position. This transformation is effective with quinazolines bearing electron-rich substituents. Therefore, the title transformations are demonstrated on the 6,7-dimethoxyquinazoline core, which is present in pharmaceutically active substances. The methodology application is showcased by transfor

Abstract:

4-Sulfonyl-1,2,3-triazole scaffolds possess promising bioactivities and applications as anion binders. However, these structures remain relatively unexplored and efficient synthetic procedures for their synthesis remain desirable. A practical room-temperature, aerobic copper-catalyzed three-component reaction of aromatic ketones, sodium sulfinates, and azides is reported. This procedure allows for facile access to 4-sulfonyl-1,5-disubstituted-1,2,3-triazoles in yields ranging from 34 to 89%.

Abstract:

The synthesis of sulfonylisoureas from thiocarbamates and sulfonyl azides via a new variant of the sulfo-click reaction is reported. Water was found to be the environmentally benign solvent of choice over various other solvents tested, and the use of any additives was not required to obtain complete conversion. The experimentally simple reaction tolerates a broad range of electron-donating and electron-withdrawing substituents attached on both the thiocarbamate and the sulfonyl azide, as shown with the synthesis of 27 sulfonylisoureas that were prepared in yields ranging from 34% to 78%.

Although the mechanical properties of the vulcanizates vary significantly with the particular di-azide used, all of them act as effective curing agents compared to a peroxide/coagent curing system. To explain the differences in properties as well as to obtain a deeper understanding of the reaction mechanism, model compound experiments are performed with 4-methylheptane as substitute for the saturated ethylene–pro

A convenient one-pot approach to the preparation of α-diazo-β-ketosulfones from sulfonyl chlorides is described.

Abstract:

A convenient one-pot synthetic protocol for the preparation of sulfonyl amidines has been developed. The procedure combines three-component reaction of sulfonyl azide, methyl propiolate and secondary cyclic amine coupling in one sequence without any solvent or catalyst and at room temperature. The reaction proceeds smoothly and a variety of desired sulfonyl amidines were obtained in moderate to good yields. This protocol has synthetic advantages in terms of low environmental impact and very short reaction time.

Abstract:

O-Methyl oximes have been employed as nucleophiles in reactions with ketenimines derived from sulfonyl azides and terminal alkynes to form N-alkylidene N′-tosylacetimidamide derivatives. The optimized conditions involved the use of CuPF6 and i-Pr2NEt in MeCN at 65 °C. Both O-methyl aldoximes and ketoximes were tolerated under the optimum conditions.

Abstract:

Staudinger reaction on the solid phase between an electronodeficit organic azide, such as sulfonyl azide, and the phosphite triester formed upon phosphoramidite coupling is a convenient method for the chemical modification of oligonucleotides at the internucleotidic phosphate position. In this work, 4-carboxybenzenesulfonyl azide, either with a free carboxy group or in the form of an activated ester such as pentafluorophenyl, 4-nitrophenyl, or pentafluorobenzyl, was used to introduce a carboxylic acid function to the terminal or internal internucleotidic phosphate of an oligonucleotide via the

Abstract:

The construction of functional hyperbranched polymers with unique topological structures and distinct properties remains a great challenge. Multicomponent polymerization, as a fascinating polymer synthetic approach, has proved to be a powerful tool for the synthesis of polymers with diverse structures and multifunctionalities, which is a great advantage for the preparation of hyperbranched polymers. In this work, a multicomponent polymerization of alkynes, sulfonyl azide, and iminophosphorane is utilized for the construction of heteroatom-rich hyperbranched poly(phosphorus amidine)s with diffe
