Stereoselective Total Synthesis of Iso‐Cladospolide B and the 12 Membered‐Macrolactone (6S,12R)‐6‐Hydroxy‐12‐methyloxacyclododecane‐2,5‐dione

Total syntheses of iso-cladospolide B (1) and the 12-membered macrolactone (6S,12R)-6-hydroxy-12-methyloxacyclododecane-2,5-dione (2), a non-natural product, were achieved from a common intermediate starting from commercially available 1,9-nonane diol.
