Organocatalytic Enantioselective Synthesis of 1,4‐Dihydropyridines [PDF]

Advanced Synthesis & Catalysis, 2017
AbstractThis review aims to bring light upon a very interesting group of compounds, the 1,4‐dihydropyridines (1,4‐DHPs). These structures are well‐known pharmacophores, used for many years to treat cardiovascular diseases because of their activity as calcium channel blockers.
