Microwave-assisted synthesis of 2,5-diarylthiazolo[5,4-d]thiazoles from benzaldehydes and dithiooxamide

Abstract

One-pot condensation of dithiooxamide with aromatic aldehydes and subsequent oxidation of intermediate 2,5-dihydro[1,3]thiazolo[5,4-d][1,3]thiazoles with selenium dioxide afforded 2,6-diaryl[1,3]thiazolo-[5,4-d][1,3]thiazoles which were characterized by 1H and 13C NMR, IR, and X-ray diffraction data.
