Abstract

Abstract [1′-14 C] Ubiquinone-2,[1′-14 C]-5-demethoxy-5-hydroxyubiquinone-2, and [1′- 14 C]-5-demethoxyubiquinone-2 have been synthesised from [1-14 C] acetic acid. A common feature of these benzoquinones is the isoprenoid chain, and the 14 C-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 ...
