A cooperative base system has been developed for the novel three component bis-heterocyclization of methylketoxime acetates. The present protocol provides an effective entry to 2-aminobenzo[4,5]thieno[3,2-d]thiazoles, e.g., I. Mechanistically, the formation of trisulfur radical anion [S3] ̇– and Willgerodt-Kindler-type sulfuration would be the key for this transformation. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Application of 2253-73-8).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application of 2253-73-8
