Divergent syntheses of two 14‐membered resorcylic acid lactones (RALs), cochliomycin B ( 6 ) and zeaenol ( 22 ), have been accomplished. The key feature in our strategy was the facile construction of three contiguous stereogenic centers in the title molecules by using natural L ‐arabinose as the chiral template. The key reactions included Takai olefination, Suzuki cross coupling, transesterification, and a late‐stage ring‐closing metathesis (RCM).
