Abstract

We established a synthetic method for the chemical isostere of the structurally unique natural product, 4′-O-methyl honokiol by replacing two allyl groups with two different alkyl groups with the aim of developing synthetic analogues of the chemical isostere. The key steps in this synthetic route are the Suzuki-Miyaura coupling reaction for the formation of the phenylpyridine moiety and the Stille coupling reaction for the stepwise introduction of two allyl groups.
