Abstract

The enantioselective synthesis of the C-14 to C-5 cyclopentane segment of jatrophane diterpenes is reported. An Evans aldol addition, a Horner–Wadsworth–Emmons olefination and a thermal intramolecular carbonyl ene reaction of an α-keto ester served as key C/C-connecting transformations. An Evans aldol addition and a thermal intramolecular carbonyl ene reaction of an α-keto esters are key steps in the asymmetric synthesis of the C-14 to C-5 segment of jatrophane diterpenes.
