An Effective Synthesis of Previously Unknown 7-Aryl Substituted Paullones

Molecules, 2023
A straightforward three-step procedure affording a wide range of novel 7-aryl substituted paullone derivatives was developed. This scaffold is structurally similar to 2-(1H-indol-3-yl)acetamides—promising antitumor agents—hence, could be useful for the ...
