Three-Component Synthesis of Thiazole-2-thione from Chalcone, Nitrobenzene and Carbon Disulfide

A convenient protocol for the synthesis of thiazole-2-thiones from nitrobenzene, chalcones and carbon disulfide is described. The construction of one C-S bond and two C-N bonds via [3+2] cycloaddition reaction is achieved using NaOH as the base in one pot. Various functional groups attached to substrates were well tolerated to afford the corresponding products in moderate to good yields. image
