N-Iodosuccinimide mediated intramolecular oxidative C(sp 2)-S bond formation for the synthesis of 2-aminobenzothiazole derivatives

An extremely efficient synthetic method for the preparation of 2-aminobenzothiazole derivatives starting from arylthioureas by using N-iodosuccinimide has been reported. This protocol features a mild reaction conditions, a short reaction time, and metal-free oxidative conditions for C (sp 2)-S bond construction.

Eosin y catalyzed visible-light-promoted aerobic oxidative cyclization of 2-aminobenzothiazole

A mild and efficient one-pot visible light irradiated synthesis of 2-aminobenzothiazole 4(a-l) from arylisothiocyanate 1(a-l) and secondary amines 2 have been reported in presence of eosin Y as an organophotoredox catalyst at room temperature under aerobi

A ligand free copper(II) catalyst is as effective as a ligand assisted Pd(II) catalyst towards intramolecular C-S bond formation via C-H functionalization

Copper(I) catalysts are usually ineffective on the other hand Pd(II) catalysts are quite effective in promoting intramolecular sp2 C-H functionalization (C-S bond formation). Herein, we have developed a ligand assisted Pd(II) catalyzed C-S bond formation via C-H activation from arylthioureas leading to the formation of 2-aminobenzothiazoles for substrates bearing electron donating (EDG) groups in the aryl ring. However without the assistance of ligand this Pd(II) catalyzed reaction is quite unproductive particularly for thioureas possessing strongly electron donating groups in the aryl rings. Interestingly, the ligand free Cu(II) catalyzed oxidative cyclization of arylthioureas are equally effective both for arylthioureas possessing electron donating as well as electron withdrawing groups in the aryl rings.
