Ionic Reactivity of 2-Isocyanoaryl Thioethers: Access to 2-Halo and 2-Aminobenzothia/Selenazoles

An ionic cascade insertion/cyclization reaction of thia-/selena-functionalized arylisocyanides has been successfully developed for the efficient and practical synthesis of 2-halobenzothiazole/benzoselenazole derivatives. This synthetic protocol, incorporating a halogen atom when forming the five-membered ring of benzothia/selenazoles, is different from the existing ones, where halogenation of the preformed benzothia/selenazole precursors happens. Additionally, a facile access to 2-aminobenzothiazoles is also achieved by the one-pot cascade reaction of 2-isocyanoaryl thioethers, iodine, and amines.

Copper-catalyzed one-pot coupling reactions of aldehydes (ketones), tosylhydrazide and 2-amino(benzo)thiazoles: An efficient strategy for the synthesis of N-alkylated (benzo)thiazoles

An efficient and practical C–N bond formation methodology for the synthesis of N-alkylated (benzo)thiazoles was developed, via the copper-catalyzed one-pot two-step reactions of 2-amino(benzo)thiazoles and aldehydes (ketones) with tosylhydrazide. This cross-coupling reaction proceeded smoothly and tolerated a broad range of functional groups (46 examples). A variety of functionalized N-alkylated (benzo)thiazoles were obtained in moderate to high yields. Notably, gram-scale synthesis of fanetizole (anti-inflammatory drug) was also realized through this protocol.

Synthesis method of 2-aminobenzothiazole compounds

The invention discloses a preparation method of 2-aminobenzothiazole compounds. The 2-aminobenzothiazole compounds is prepared from the following steps of dissolving phenyl/naphthalene isothiocyanateand primary amine into a solvent, adding a catalyst iodine and an oxidant, carrying out one-pot multi-step tandem reaction to prepare the 2-aminobenzothiazole compounds under the temperature of 80 to 150 DEG C. The synthesis method has the advantages that raw materials are cheap and easily available, the reaction condition is mild, the substrate application range is broad, atom economy is high, requirements of green chemical are met, and a novel method which is economical and practical and green and environmentally friendly is provided for synthesis of the 2-aminobenzothiazole compounds.
