Abstract:

Spiroketal-containing natural products are found ininsects, plants, bacterial, and marine sources. Thesenatural products often display remarkable biologicalactivity and their stereocontrolled synthesis remains achallenge.1 Within this context, a gold-catalyzed synthesisof unsaturated spiroketals was accomplished by our groupvia dehydrative cyclization of monopropargylic triols.
