Abstract
The cross‐coupling study of gem‐dibromoesters with triarylbismuths as threefold arylating reagents was investigated under palladium‐catalyzed conditions. This study using triarylbismuth reagents explored the cross‐coupling reactivity with various functionalized gem‐dibromoesters. It furnished a variety of multi‐functional trisubstituted acrylates embedded with aryl, alkene and alkyne scaffolds in high yields. The present study in turn, provided easy access to various triarylated acrylates and functionalized 1,3‐dienyl and 1,3‐enyne esters. Further, the established method applied in the step‐economic and convergent synthesis of quebecol natural product in good yield.
