Mechanism of Biosynthesis of ß-Diketones and Alkan-2-OL Esters from Epicuticular Waxes

  • Giorgio Bianchi


Long chain aliphatic ß-diketones and alkan-2-ol esters are common constituents of plant surface lipids1. The ß-dicarbonyl pattern, two carbonyl groups 1, 3 one another, has suggested that the biosynthesis of ß-diketones involves condensation of appropriate ß-ketoesters and esters, via a ‘biological Claisen reaction’2. An alternative route has been advanced according to which ß-diketones are generated by an elongation-decarboxylation reaction on a protected ß-keto acid precursor3.
