Diiiodine/Potassium Persulfate Mediated Synthesis of 1,2,3-Thiadiazoles from N -Tosylhydrazones and a Thiocyanate Salt as a Sulfur Source under Transition-Metal-Free Conditions

A highly efficient method for the synthesis of 1,2,3-thiadiazoles has been developed by utilizing readily available tosylhydrazones and ammonium thiocyanate with ecofriendly EtOH as the solvent at room temperature. The reaction shows a wide scope of subst

Synthesis method of 1, 2, 3-thiadiazole derivative

The invention belongs to the technical field of compound preparation, and discloses a synthesis method of a 1, 2, 3-thiadiazole derivative. The synthesis method of the 1, 2, 3-thiadiazole derivative comprises the following steps: taking an N-tosylhydrazon

Selective transformations of 2-(p-toluenesulfonyl)-N-tosylhydrazones to substituted 1,2,3-thiadiazoles

Selective transformations of 2-(p-toluenesulfonyl)-N-tosylhydrazones with different sulfur sources have been established. A series of 4-aryl-1,2,3-thiadiazoles and novel 4-aryl-5-tosyl-1,2,3-thiadiazoles were selectively constructed by the adjustment of reaction conditions. These protocols feature short reaction time, good compatibility of functional group, easily available materials, and good selectivity.

Metal- and Oxidant-free Electrosynthesis of 1,2,3-Thiadiazoles from Element Sulfur and N-tosyl Hydrazones

A metal- and oxidant-free electrochemical method for synthesizing 1,2,3-thiadiazoles by inserting element sulfur into N-tosyl hydrazones is reported. This electrochemical transformation engages electrons as reagents to achieve redox processes, and avoid e

Perylenequinonoid-Catalyzed [4 + 1] and [4 + 2] Annulations of Azoalkenes: Photocatalytic Access to 1,2,3-Thiadiazole/1,4,5,6-Tetrahydropyridazine Derivatives

Nitrogen-containing heterocycles are especially considered "privileged" structural scaffolds for the development of new drugs. However, traditional methods of organic synthesis are mainly based on thermal cycloaddition reaction; thus, the exploration of n

Formation of reagent-selective products from 2-(4,5-dihydrothi- azol-2-ylthio)-1-arylethanone with different nucleophiles

The reactions of 2-(4,5-dihydrothiazol-2-ylthio)-1-arylethanone with different nucleophiles including semicarbazide hydrochloride, hydroxylamine hydrochloride, hydrazine, ethylenediamine and aminoethanol have been investigated, and the formation of a variety of products with different reagents is highlighted.
