Electric Literature of 19989-64-1, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.19989-64-1, Name is Ethyl benzo[d]thiazole-6-carboxylate, molecular formula is C10H9NO2S. In a patent, introducing its new discovery.
Copper-Promoted Cycloaddition of alpha-Methylenyl Isocyanides with Benzothiazoles: Tunable Access to Benzo[d]imidazothiazoles
A tunable route to both isomers of benzo[d]imidazothiazole has been developed through copper-promoted cycloaddition of alpha-methylenyl isocyanides with benzothiazoles. When the C2 position of benzothiazole is linked to a C-H or C-C bond, benzo[d]imidazo[2,1-b]thiazoles are obtained through a novel rearrangement via C-S bond cleavage and formation of a new C-S bond. When 2-chloro- or 2-bromobenzothiazoles are used under the same reaction conditions, the isomeric benzo[d]imidazo[5,1-b]thiazoles are formed selectively. These reactions proceed smoothly in moderate to excellent yields at room temperature, and a wide range of functional groups are tolerated.
