title: The first enantioselective synthesis of cytotoxic marine natural product palau'imide and assignment of its C-20 stereochemistry.
abstract: Methyl tetramate derivative 6 has been developed as a new building block for the flexible and racemization-free synthesis of methyl 5-benzyl-3-methyltetramate via alkylation, and used in the first asymmetric synthesis of palau'imide (1). This allowed the establishment of the hitherto unknown stereochemistry at the C-20 of palau'imide as S.
