Total synthesis and absolute configuration of (-)-anthoplalone

We report the total synthesis of the cytotoxic agent (-)-anthoplalone and the determination of its absolute stereochemistry. The cyclopropane moiety was prepared using a nonracemic bicyclic chloroallyl phosphonamide anion addition to tert-butyl 3,3-dimethyl acrylate. Several pathways were studied to secure the E-trisubstituted olefin of the left part of the molecule.
