Synthesis method of aryl tertiary sulfonamide compounds promoted by visible light

The invention provides a synthesis method of aryl tertiary sulfonamide compounds promoted by visible light. In a non-protonic solvent, N-benzyl tertiary amine and arylsulfonyl chloride are used as rawmaterials, under the conditions of photosensitizer catalysis and illumination, a reaction is carried out for 1-4h at room temperature, and then separation and purification are carried out to obtain the product. The synthesis method of the aryl tertiary sulfonamide compound provided by the invention has the advantages of mild reaction conditions, simplicity and convenience in operation, short reaction time, no need of any transition metal catalysis and environmental friendliness.

Controlled synthesis of N, N-dimethylarylsulfonamide derivatives as nematicidal agents

Gramine can be intelligently and efficiently supplied with N, N-dimethylamino group and then reacted with the corresponding sulfonyl chlorides to synthesize N, N-dimethylarylsulfonamides. We herein designed and controlled synthesis of N, N-dimethylarylsulfonamide derivatives, and first reported the results of the nematicidal activity of 15 title compounds 3a-o against Meloidogyne incongnita in vitro, respectively. Among all of the title derivatives, compounds 3a, 3c, 3k, and 3o exhibited potent nematicidal activity with median lethal concentration (LC50) values ranging from 0.22 to 0.26 mg/L. Most noteworthy, N, N-dimethyl-4-methoxyphenylsulfonamide (3c) and N, N-dimethyl-8-quinolinesulfonamide (3o) showed the best promising and pronounced nematicidal activity, with LC50 values of 0.2381 and 0.2259 mg/L, respectively.

Preparation method of N,N-dimethylsulfamide derivatives

The invention discloses a preparation method of N,N-dimethylsulfamide derivatives and belongs to the technical field of synthesis of medical compounds. The preparation method comprises the following steps: reacting gramine, a reactant with sulfonyl chloride groups and an alkaline substance with any one of solvents such as CH2Cl2, CH3COCH3 and CH3CN at a temperature of minus 15 DEG C to 80 DEG C for 24-48 hours so as to obtain the product, wherein the molar ratio of the gramine to the reactant to the alkaline substance is (1.0-2.0):(1.2-4.0):(1.5-6.0). The N,N-dimethylsulfamide derivatives can be simply and efficiently prepared withlow cost, and the yield is up to 70-98%.

Charge-Transfer Complex Promoted Regiospecific C?N Bond Cleavage of Vicinal Tertiary Diamines

A catalyst-free, charge-transfer complex promoted coupling of sulfonyl chlorides with vicinal tertiary diamines to generate sulfonamides is presented. Mechanistic studies showed that these reactions are proceeded via charge transfer of vicinal tertiary diamines to sulfonyl chlorides, forming the unstable sulfonyl quaternary ammonium like complexes which induced the regiospecific intramolecular C?N bond cleavage of vicinal tertiary diamines. (Figure presented.).

Potassium tert-butoxide-mediated metal-free synthesis of sulfonamides from sodium sulfinates and N,N-disubstituted formamides
