equivalents containing a Weinrebamide as one of the functionalities have been synthesized from commercially available o-, m-, and p-toluic acid. These bifunctional buildingblocks enabled efficient C-C bond formation through Wittig reaction with simple and functionalized aldehydes on one hand and a clean nucleophilic addition of 3,4,5-trimethoxy phenylmagnesium bromide onto the Weinrebamide functionality on
