Abstract

Novel star-shaped threefold dihydropyridine (5) and xanthene derivatives (8) have been synthesized using a highly efficient one-pot procedure. Phloroglucinol (1) and Mannich bases (2) have been used as readily available starting materials. The hydrogen bonding in dihydropyridine derivative (5) is characterized by an uncommon high kinetic stability.
