Abstract

Three bioactive prenylated isoflavone natural products were synthesized for the first time, using a combination of Pd-catalyzed Suzuki–Miyaura coupling for installing the B-ring, microwave-promoted Claisen rearrangement of allyl ethers, and Ru-catalyzed olefin cross metathesis for obtaining the prenyl substituents. Careful consideration of the protecting group strategy turned out to be vital for the success of these total syntheses.
