Synthesis of the geranylated dihydrostilbenoid amorfrutin B with antimicrobial, PPARγ modulating and quorum sensing inhibitory activities has been achieved from amorfrutin A ethyl ester by a seven-step sequence involving the Johnson–Claisen rearrangement to install the (E)-configured double bond on the side chain. The proposed stereoisomer of amorfrutin D and its enantiomer have been synthesized enantioselectively from the same starting material, both in nine steps, using the CBS asymmetric reduction as the key step.
