We report the first totalsynthesis of the proposedstructure of ardimerin, which was achieved in 14 steps starting from 2,3,4‐trimethoxybenzoic acid. The key steps include the β‐selective formation of the crucial C‐glycoside linkage and stepwise construction of the strained eight‐membered salicylide core. The synthesis revealed that the proposedstructure 1 does not match the natural product. A proposal
