The first preparation of the antimalarial natural product decursivine is described. A Diels–Alder/Plieninger indolization protocol allows convenient preparation of the indole 15 which, in turn is a suitable substrate for a boron–enolate aldol reaction with piperonal (16). The resulting adduct 14 is transformed efficiently to the natural product. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim,
