When 4,6,7-trichloro-5-hydroxy-2-(2-pyrimidylamino)- 2,3-dihydrobenzo[b]furan reacted with phenyliodoso diacetate, an unexpected oxidative recyclization was observed to give 3-(3,5,6-trichloro-1,4-benzoquinon-2-yl)imidazo[1,2-a]pyrimidine. 2-[N-2-(3,

4,6,7-Trichloro-2-hetarylamino-5-hydroxy-2,3-dihydrobenzo[b]furans have been prepared from 4,6,7-trichloro-2,5-dihydroxy-2,3-dihydrobenzo[b]furan and hetarylamines. Reductive opening of the dihydrobenzofuran ring in these compounds gave 3,5,6-trichlo

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
