Synthesis and Fluorescent Properties of Novel Isoquinoline Derivatives.

Isoquinoline derivatives have attracted great interest for their wide biological and fluorescent properties. In the current study, we focused on the synthesis of a series of novel isoquinoline derivatives substituted at position 3 of the heteroaromatic ring. Compounds were obtained in a Goldberg-Ullmann-type coupling reaction with appropriate amides in the presence of copper(I) iodide, ,-dimethylethylenediamine (DMEDA), and potassium carbonate.
