Zhu, Hui; Zhang, Shi-Bo; Liu, Xing; Cheng, Yu; Peng, Han-Ying and Dong, Zhi-Bing (2018): Copper(II)-Promoted Cascade Synthesis of 2-Aminobenzothiazoles Starting from 2-Iodoanilines and Sodium Dithiocarbamates. In: European Journal of Organic Chemistry, No. 41: pp. 5711-5716

A facile and efficient formation of 2-aminobenzothiazoles by a copper(II)-promoted one-pot cascade process was developed. The desired 2-aminobenzothiazoles were synthesized in good to excellent yields (up to 97 %) in the presence of Cu(OAc)(2) and K2CO3, a variety of functional groups on 2-iodoanilines could be tolerated. The method features ligand-free and mild reaction conditions and good yields, illustrating its practical synthetic value in some potentially biologically active compounds.
