The isoquinoline and dihydroisoquinoline ring systems are found as the core nucleus in a wide variety of natural products and pharmaceutical agents with good biologically activity. Isoquinoline, benzoxazine-fused isoquinlines and pyrazo-lo[5,1-a]isoquinolines are prepared from o-alkynyl aldehydes and nitrogen-containing compounds via tandem reactions catalyzed by CuI or AgNO3. The reactions have some advantages, such as mild reaction conditions, simple operation and easily available catalysts.

Key words: isoquinoline, benzoxazine-fused isoquinlines, pyrazolo[5,1-a]isoquinolines, o-alkynyl aldehydes, tandem reaction
