CrocaginA (1) combines an attractive molecular structure with an unusual biosynthesis and bioactivity. An efficient synthesis of crocaginA is presented that hinges on an early formation of the heterotricyclic core, an electrophilic amination, and the stereoselective hydrogenation of a tetrasubstituted double bond. This synthesis confirms the absolute configuration of crocaginA and provides access to the natural product and derivatives thereof for further biological testing.
