Microwave-assisted Bischler-Napieralski or Pictet-Spengler reactions allowed the production of substituted isoquinoline libraries. The generated dihydroisoquinolines and tetrahydroisoquinolines could be oxidized to their corresponding isoquinoline analogues. A more practical and efficient route to C1- and C4-substituted isoquinolines involves the preparation and activation of isoquinolin-1(2H)-ones.
