Abstract
An efficient one-pot method for the synthesis of previously unknown of 2,5-bis(pyrazol-4yl)[1,3]thiazolo[5,4-d][1,3]thiazoles has been developed. The method comprises the microwaveassisted reaction of dithiooxamide with pyrazole-4-carbaldehydes followed by oxidation of the initially formed 2,5-dihydro[1,3]thiazolo[5,4-d][1,3]thiazoles with selenium dioxide. 2,5Bis(pyrazol-4-yl)[1,3]thiazolo[5,4-d][1,3]thiazoles were characterized by 1H, 13C and 15N NMR, IR spectroscopy and X-ray diffraction data.
