Christian Knittl-Frank reports on the development of a novel synthetic route to the naturally occurring polyhydroxylated oleanane, hederagonic acid. Polyhydroxylated oleananes are a vast family of naturally occurring triterpenoids with versatile biological activities. A low commercial availability combined with high prices make these molecules interesting targets in natural product synthesis. The developed synthetic approach starts from oleanolic acid, a cheap material that is commercially available in bulk quantities. It features several multi-step one-pot reactions, allowing a minimization of the number of steps and reducing the preparative effort. Importantly, catalytic C–H functionalization was achieved at unusually low temperatures. Hederagonic acid was thus prepared in as little as four steps, resulting in the shortest semisynthesis of this oleanane to date.
