Abstract
The synthesis of new tricyclic derivatives having sulfur-containing six or seven-membered rings fused to the <<a>> edge of benzimidazole system, is re ported. The stereochemical characteristics of thiazino- and thiazepinobenzi midazoles (4-7) are described and comparative NMR data are discussed. The s ynthetic approach to new benzo- or pyridothiazinobenzimidazole tetracyclic systems (8) is also reported.
