2-Amino-5-arylazothiazoles 5 reacted with chloroacetyl chloride to afford the chloro-acetamide derivatives 6 which further reacted with 2-mercaptobenzothiazole to furnish a new series of 5-arylazothiazolyl dyes 7. The azo structure of the dyes (rather than the tautomeric hydrazo structure) was ...
Benzothiazole derivatives are important classes of heterocyclic compounds that occur widely in the pharmaceutical industry. For example, compounds containing a 2-aminobenzothiazole motif have attracted an interest because they exhibit a wide range of biological activities such as antifungal [2], anti-...

A useful and efficient method of preparing an alkylated thiazoline carboxylic acid, or a derivative thereof, comprises coupling a substituted aryl nitrile such as, for example, 2,4-dimethoxybenzonitrile or 4-methoxybenzonitrile, with a cysteine ester to form a substituted thiazoline carboxylic acid es...
