[1′-14C]Ubiquinone-2, [1′-14C]-5-demethoxy-5-hydroxyubiquinone-2, and [1′-14C]-5-demethoxyubiquinone-2 have been synthesised from [1-14C]acetic acid. A common feature of these benzoquinones is the isoprenoid chain, and the 14C-label has therefore been incorporated in this isoprenoid. The coupling of the different quinone head groups and the isoprenoid chain is the last step in the total synthesis, to prevent unnecessary loss of the labelled material during synthesis. The products have been characterised by mass spectrometry, 1H NMR and 13C NMR.

Optically active 3-alkoxy-6-hydroxymethyl-6-methyl-2-cyclohexenone and 6-acetoxymethyl-3-alkoxy-6-methyl-2-cyclohexenone were efficiently obtained by lipase-catalyzed kinetic resolution. (R)-6-Acetoxymethyl-3-(methoxymethoxy)-6-methyl-2-cyclohexenone was converted to the synthetic intermediate of cassiol.
