Herein we present the first organic synthesis of two potentially bioactive lycopene metabolites, namely, 10 0-apolycopen-10 0-oic acid (6) and 14 0-apolycopen-14 0-oic acid (13), which were obtained in their (all-E) stereoisomeric forms using Wittig and Horner-Wadsworth-Emmons type coupling reactions. Both molecules are shown to up-regulate the carotenoid asymmetric cleavage enzyme BCO2 while having no effect on BCO1 expression.
