Enantioselective total syntheses of the Kopsia alkaloids (+)‐grandilodine C and (+)‐lapidilectine B were accomplished. A key intermediate, spirodiketone, was synthesized in 3 steps and converted into the chiral enone by enantioselective deprotonation followed by oxidation with up to 76 % ee. Lactone formation was achieved through stereoselective vinylation followed by allylation and ozonolysis. The total synthesis of (+)‐grandilodine C was achieved by palladium‐catalyzed intramolecular allylic amination and ring‐closing metathesis to give 8‐ and 5‐membered heterocycles, respectively. Selective reduction of a lactam carbonyl gave (+)‐lapidilectine B. The absolute stereochemistry of both natural products was thereby confirmed. These syntheses enable the scalable preparation of the above alkaloids for biological studies.
