The products of the one-pot, three-component synthesis of [1,3]thiazolo-[4,3-b][1, 3, 4]thiadiazoles from aromatic aldehydes, thioglycolic acid, and compounds containing a C(=S)–N–NH2 fragment (thiosemicarbazide or 4-amino-2,4-dihydro-3H-1,2,4-triazole-3-thiones) are not condensed hetero-cycles (as reported by several researchers), but are thiosemicarbazones or triazolylimines of the aldehydes used.
