Abstract

A biomimetic, regio- and stereoselective approach to the 5,6,11-tricyclic core skeleton of xenovulene A, as well as sterhirsutins A and B, is described. The key steps are a biomimetic inverse-electron-demand hetero-Diels-Alder cycloaddition of α-humulene and a ribose-derived vinyl ketone, followed by acid-catalyzed rearrangement of the 1,3-dioxolane that neighbors the resultant cyclic enol ether.
