product (±)‐goniomitine was synthesized by a method featuring two key steps: 1) fragment coupling to a functionalized cyclopentene by a novel palladium‐catalyzed decarboxylative vinylation reaction and 2) an unprecedented one‐pot integrated oxidation/reduction/cyclization (IORC) process to convert the substituted cyclopentene into the tetracyclic skeleton of goniomitine with high chemo‐, regio‐, and diastereoselectivity
