Enantioselective synthesis of a diastereomer of iriomoteolide-1a. What is the correct structure of the natural product?

(Figure Presented) An enantioselective approach to a diastereomer of iriomoteolide-1a is described. Highlighted is a SmI2-mediated intramolecular reductive cyclization approach to complex cyclic hemiketals. An acetylide-chloroformate coupling strategy is also featured. Our results show that the structures of iriomoteolide-1a-1c require careful reassessment.
