Isocyanide-Induced Esterification of Sulfinic Acids to Access Sulfinates

The isocyanide-induced esterification of sulfinic acids with alcohols or thiophenols access to sulfinates has been developed. Various primary, secondary, and tertiary alcohols could be compatible with the established protocols. Notably, such an isocyanide-induced synthetic strategy presented the advantages of simple operation, good functional group tolerance, and more than 40 examples up to 99% yields. (Figure presented.).

NaHSO3-Mediated Direct Synthesis of Sulfinic Esters from Sulfonyl Hydrazides under Transition-Metal-Free Conditions

We have developed a protocol for the NaHSO3-promoted esterification of sulfonyl hydrazides with alcohols for the synthesis of sulfinic esters. Various sulfonyl hydrazides could be converted to the corresponding sulfinic esters in good to high yields. The merits of this protocol include mild transition-metal-free reaction conditions, an inexpensive and available reagent, and operational simplicity. Controlled experiments reveal that this transformation probably undergoes via a radical pathway. (Figure presented.).

Efficient electrosynthesis of sulfinic esters via oxidative cross-coupling between alcohols and thiophenols

A new protocol for S O bond formation was developed by electrochemical oxidative cross-coupling between alcohols and thiophenols. With this strategy, a series of valuable sulfinic ester derivatives were synthesized up to 96% yield from basic starting materials. A preliminary mechanistic investigation reveals that this reaction involves oxygen reduction reaction (ORR).

Electrochemical Synthesis of Sulfinic Esters via Aerobic Oxidative Esterification of Thiophenols with Alcohols

A method for the electrochemical synthesis of sulfinic esters by aerobic oxidative coupling of thiophenols and alcohols has been developed. Using electrons as the redox reagent and O 2in air as the oxygen source, the reactions proceeded smoothly at room temperature, even for a gram-scale preparation. No use of catalyst, clean redox reagent, green and abundant oxygen source, and mild reaction conditions make this strategy eco-friendl.

A sustainable oxidative esterification of thiols with alcohols by a cobalt nanocatalyst supported on doped carbon

Here, we developed a new cobalt nanocatalyst supported on N-SiO2-doped activated carbon (Co/N-SiO2-AC), which exhibits excellent catalytic performance towards the oxidative esterification of (hetero)aryl and alkyl thiols with alcohols. A wide array of sulfinic esters were efficiently afforded in an exclusive chemoselective manner. The developed synthetic method proceeds with the merits of mild reaction conditions, broad substrate scope, operational simplicity, good functional group tolerance, earth-abundant and reusable cobalt catalysts, the utilization of renewable alcohols as the coupling partners and molecular O2 as the sole oxidant, which offers a practical method for sustainable synthesis of sulfinic esters.

2-AMINO-N-(ARYLSULFINYL)-ACETAMIDE COMPOUNDS AS INHIBITORS OF BACTERIAL AMINOACYL-TRNA SYNTHETASE

The present invention pertains generally to the field of therapeutic compounds. More specifically the present invention pertains to certain 2-amino-N-(arylsulfinyl)- acetamide compounds that, inter alia, inhibit (e.g., selectively inhibit) bacterial amino

Copper-Catalyzed Aerobic Oxidative Reaction of Sulfonyl Hydrazides with Alcohols: An Easy Access to Sulfinates

A Cu-catalyzed aerobic oxidative reaction between sulfonyl hydrazides and alcohols has been developed. In this reaction, sulfonyl hydrazides act as the sulfinic acid precursors to react with alcohols, resulting in sulfinic esters with up to 72 % yield. This catalytic system tolerates a wide range of sulfonyl hydrazide substrates, and represents a new strategy for the transformation of readily available sulfonyl hydrazides.
