A ruthenium catalyzed intramolecular C-S coupling reaction of N-arylthioureas enables the synthesis of 2-aminobenzothiazoles via an electrophilic ruthenation pathway instead of a direct C-H activation. In case of meta-substituents on the N-arylthiourea, stereoelectronic effects dictate the final regioselective outcome of the reaction.
