Reactions of Dipivaloylketene Dimer with Nucleophiles: New Access to the 2,6,9-Trioxabicyclonona-3,7-diene Ring System (Bridged Bis-Dioxines)

Novel and convenient methods to prepare several functionalized 2,6,9-trioxabicyclononadienes ("bridged bis-dioxines") 6, 10, 11, and 12 are described.In general, these are obtained by addition of nucleophiles to α-oxoketene 5 in a multistep reactio
