摘要

Several 2-(2-phenylethyl) chromones have been shown to possess neuroprotective activity. However, limited synthetic methods have been disclosed to construct the 2-(2-phenylethyl) chromone skeleton. Herein, we report a straightforward 3-step preparation of five naturally occurring 2-(2-phenylethyl) chromones utilizing the Claisen condensation as the key step.
