The transformation of (±)-15-norsolavetivone and related compounds, into (±)-lubimin and (±)-oxylubimin, which constitutes the totalsynthesis of these highly oxygenated spirovetivane phytoalexins, is described.
The isolation and structure elucidation of the title spirovetivane sesquiterpenes, stress metabolites produced in diseased potato tubers, are described.
The configuration of oxylubimin was determined on the basis of the NMR spectrum in the presence of the shift reagent and the CD spectrum of oxylubimin derivatives.
