title: Synthesis and chromatography of [CpRu]+-complexed bastadin precursors.
abstract: The eastern and western diaryl ether portions of the macrocyclic bastadins, natural products from the marine sponge Ianthella sp., have been assembled as [CpRu]+ complexes. In an HPLC study, aminopropyl-functionalised silica was found as a very suitable stationary phase for the chromatographic separation of the different cationic ruthenium sandwich complexes. It is now possible for the first time to effectively monitor and purify [CpRu]+ complexes and to carry them through several synthetic steps.
