Synthesis of the C16-C28 spiroketal Subunit of spongistatin 1 (altohyrtin A): The pyrone approach

(Equation presented) The synthesis of the CD spiroketal fragment of spongistatin 1 (altohyrtin A) has been accomplished utilizing the addition of a metalated pyrone to an aldehyde and subsequent acid-catalyzed spirocyclization. A stereoselective hydrogena
