The bicyclic core of ent-lomaiviticin A was prepared in 11 operations from (S)-1-phenyl-2-propyn-1-ol in a two-directional route that features (1) a double Ireland Claisen rearrangement and (2) a double olefin metathesis reaction to form the key C C bonds of the target.

a two-directional, divergent approach featuring (1) a double Ireland Claisen rearrangement to establish key core bonds with correct relative stereochemistry and (2) a double olefinmetathesis reaction to deliver both cyclohexene rings of the target.
