A method is provided for synthesizing xanthohumol by inserting a prenyl-group onto the aryl-ring via a para-Claisen rearrangement after using a Mitsunobu reaction to establish the key prenylether precursor. A Claisen-Schmidt condensation is used to construct the chalcone scaffold followed by removal of MOM protecting groups under acidic conditions that are optimized to prevent concomitant cyclization to the flavone.
