Synthesis of a Potent Antimalarial Amphilectene

7-Isocyano-11­(20),14-epiamphilectadiene, the most potent of antimalarial amphilectenes, is synthesized in seven steps from readily available materials. The synthesis is enabled by a new dendrimeric triene (Danishefsky [3]-dendralene) and a new method for stereo- and chemoselective isocyanation. This chemistry provides a useful entry into an underexplored yet promising family of antimalarial terpenoids
