Licochalcones, derived from the dried roots of Glycyrrhiza inflata, have been reported to show various biological activities including antitumor, antiparasitic, antileishmanial, antioxidative, superoxide scavenging, antibacterial, and PTP1B activity. Licochalcone D has an allyl group on ring A instead of ring B, however, most other natural licochalcones possess the group on ring B. Total synthesis of licochalcone D has not been reported even possessing the strongest anti-inflammatory activity. Therefore, the first total synthesis of licochalcone D has been developed by using water-accelerated [3,3]-sigmatropic rearrangement method.

Licochalcone C was synthesized from commercially available 2,4-dihydroxybenzaldehde by using regioselective $Al_2O_3$-mediated C-prenylation followed by conventional Claisen-Schmidt condensation in basic condition.
