An air-tolerant Cu-catalyzed sulfonylative Hiyama cross-coupling reaction enabling the formation of diaryl sulfones is described. Starting from aryl silanes, DABSO and aryliodides, the reaction tolerates a large variety of polar functional groups (amines, ketones, esters, aldehydes). Control experiments coupled with DFT calculations shed light on the mechanism, characterized by the formation of a Cu(I)-sulfinate intermediate via fast insertion of a SO2 molecule.

Paragraph 0144-0148, (2021/03/31)
The invention belongs to the technical field of compound preparation, and particularly relates to a method for synthesizing sulfone compounds under a photocatalysis condition. Aromatic hydrazine and sulfinate are used as raw materials, and under the action of alkali and a solvent, a sulfone compound is generated through reaction under the condition of air or oxygen under the illumination of visible light. According to the method disclosed by the invention, aryl hydrazine is used as an arylation reagent, polyacid salt is used as a catalyst or an organic photosensitizer is used as a catalyst, and the sulfones compound can be efficiently synthesized by coupling with sulfinate under the condition of room temperature through visible light irradiation. The method has good substrate universalityand relatively mild reaction conditions, is not only a substitute for synthesizing sulfone compounds by coupling from simple substrates reported at present, but also broadens the new application of the polyacid salt in the field of photocatalysis.

Paragraph 0704-0710; 0712; 0714-0715; 0717-0720; 0722-0725, (2021/04/29)
The present invention relates to a method for manufacturing a sulfone and sulfonyl derivative compound using sodium (tert-butyldimethylsilyl)oxymethanesulfinate, which is a novel organic sulfin salt, wherein the novel organic sulfin salt has good stability, environmental friendliness and economy, and is easy to handle, and thus significantly reduces the amount of transition metal catalysts and the amount of organic sulfin salts used when introducing aryl or alkenyl. Also, alkylation, arylation, amination, and fluorination are all possible during secondary functionalization. Therefore, the present invention can be usefully used in preparation and mass production of various kinds of sulfones and derivatives thereof including asymmetric sulfone derivatives.
Silyloxymethanesulfinate as a sulfoxylate equivalent for the modular synthesis of sulfones and sulfonyl derivatives

, p. 13071 - 13078 (2021/01/09)
An efficient protocol for the modular synthesis of sulfones and sulfonyl derivatives has been developed utilizing sodium tert-butyldimethylsilyloxymethanesulfinate (TBSOMS-Na) as a sulfoxylate (SO22-) equivalent. TBSOMS-Na, easily prepared from the commercial reagents Rongalite and TBSCl, serves as a potent nucleophile in S-alkylation and Cu-catalyzed S-arylation reactions with alkyl and aryl electrophiles. The sulfone products thus obtained can undergo the second bond formation at the sulfur center with various electrophiles without a separate unmasking step to afford sulfones and sulfonyl derivatives such as sulfonamides and sulfonyl fluorides.

An efficient cross-coupling of sodium or lithium sulfinates with aryl iodides, using a combination of nickel and photoredox catalysis, is described. The dual catalyst system enables a versatile synthesis of aryl sulfones at room temperature in good yields and displays a broad functional group compatibility. The potential utility of this method in the late-stage diversification of complex molecules and in the conversion of organolithium reagents and sulfur dioxide into sulfones is demonstrated.
METHODS OF INHIBITING BACTERIAL VIRULENCE AND COMPOUNDS RELATING THERETO

Paragraph 0211, (2017/01/31)
The present invention relates to compounds and methods for the treatment of bacterial infections. Because their mechanism of action does not involve killing of bacteria or inhibiting their growth, the potential for these compounds to induce drug resistance in bacteria is minimized. Through inhibiting bacterial virulence, the present invention provides a novel means of treating bacterial infections.
