| Abstract: | We report a highly stereoselective palladium(II)-catalyzed intramolecular cyclization of 1,11-dihydroxyundec-9-en-5-one derivatives via unstable hemiacetal intermediates, in which cyclization occurs without activation of the allylic alcohol to afford spiroketal structures. |
| Keywords: | Spiroketal Palladium(II)-catalyst Hemiketal Dihydroxyketone |
