A simple and efficient method for removal of phenolic methoxymethyl ethers in the presence of 30?mol% of bismuth trichloride in acetonitrile/water is described. Notable features of the cleavage protocol entail use of an ecofriendly bismuth reagent, ease of handling, low cost, operational simplicity, and good functional group compatibility. A number of structurally varied phenolic methoxymethyl ethers were cleaved in good to excellent yields.

Pawhuskin A is an isoprenylated stilbene that was isolated from Dalea purpurea and reported to have affinity for the opioid receptor in vitro. It has been synthesized through a convergent sequence that joins a prenylated aldehyde with a geranylated phosphonate in a stereoselective Horner-Wadsworth-Emmons condensation to afford the target E olefin isomer. This synthesis confirms the structure assigned to the natural product and establishes a route that may be used to explore its biological activity and to prepare more active analogues.
