The total synthesis of the 14‐membered resorcylic acid lactone neocosmosin A is described. The key step in the synthesis is the palladium‐catalyzed α‐arylation of TES‐enol ethers of enones. The employment of the α‐arylation approach to this class of resorcylic acid lactones is a new approach, which has the scope of being generalized into a unified approach for the synthesis of this class of natural...
