Abstract

We have synthesized novel condensed heterocyclic derivatives of benzofuran by reaction of 2,5-dihydroxy3, 4, 6, 7-tetrachloro-2, 3-dihydrobenzo[b]furan (I) with 4-phenyl- and 4-methylthiosemicarbazides, diphenylthiocarbazone, and also via cyclization of 2, 5-dihydroxy-4, 6, 7-trichloro-3-(N, N-diethyldithio-carbarnoyl)-2, 3dihydrobenzo[b]furan (obtained in the reaction of benzofuran I with sodium NN-dithiocarbamate).
