Zusammenfassung Entsprechend substituierte Thieno[2,3-c]thiopyrane (2, 3, 5, 6, 10, 11) wurden in 1,5,6,8-Tetrahydro-2H-thiopyrano[4′,3′:4,5]thieno[2,3-d]pyrimidin-4(3H)-one (4, 7, 12) umgewandelt, welche als Schlüssel-Zwischenprodukte für Thiazol- und 1,3-Thiazin-Anellierungen zu den tetracyclischen Zielstrukturen7, 8, 9 und13 dienten; diese leiten sich von zwei neuen heterocyclischen Ringsystemen ab.
Notes:
Summary Appropriately substituted thieno[2,3-c]thiopyrans (2, 3, 5, 6, 10, 11) were converted into 1,5,6,8-tetrahydro-2H-thiopyrano[4′,3′:4,5]thieno[2,3-d]pyrimidin-4(3H)-ones (4, 7, 12). These in turn were used as key intermediates for annelations of thiazolo and 1,3-thiazino moieties to yield the tetracyclic target structures7, 8, 9, and13, derived from two novel heterocyclic ring systems.
