protecting groups to distinguish positions on the A-ring from the B-ring of the stilbenoid was paramount for the success of this project. Methylation of the C-4′ phenolic moiety by removal of the tert-butyldimethylsilyl protecting group in the presence of methyl iodide was accomplished in excellent yield without significant Z to E isomerization. This step (carried out with 12C-methyl iodide as proof of concept
