Abstract
Suzuki-Miyaura and Sonogashira cross-coupling reactions were efficiently employed for the syntheses of aryl, biaryl, and aryl alkynyl substituted polycyclic tetrahydropyrimidinium, diazepanium, and diazocanium derivatives with moderate-to-high yields. Appropriately functionalized pyridinium templates for these syntheses were obtained under microwave irradiation, using basic alumina as the solid support.
Key words
Suzuki-Miyaura - Sonogashira - cross-coupling - fused rings - diazepanium - diazocanium
