The full absolute configuration assignment of phosphoeleganin (1), a recently discovered marine-derived phosphorylated polyketide with protein tyrosine phosphatase 1B inhibitory activity, was achieved. It was based on the synthesis of model diasteroisomeric compounds of the C-8–C-12 segment portion of phosphoeleganin, chiral derivatization methods, and application of the universal NMR database concept.
