condensation, oxidation and thiation to afford 6a–i , 7a–c , and 4-thioxo 8a–c , respectively. A new fluorenespiro-thiazolo-benzimidazole 10 was also obtained in one step via cyclocondensation of 1,2-phenylenediamine, 9-fluorenone and 2-mercaptoacetic acid. The obtained products seem to be interesting from the biological point of view.
