Efficient synthetic routes to the four isomers 17b-20b of the title ketone are described. Entry begins from the Wieland-Miescher homologue 3 whose pair of carbonyl groups are amenable to regiochemical manipulation. The compositions of the reaction mixtures generated under kinetic or thermodynamic control were defined by H-1 NMR analysis subsequent to chromatographic purification. The regiochemical trends are correlated with B3LYP/6-31G* calculations, the results of which conform to the preferred introduction of a 1,2.- or 2,3-double bond.
