A novel protocol for the synthesis of furo[2,3-b]benzofurans and dihydrofuro[2,3-b]benzofurans
Abstract
A Wittig olefination–Claisen rearrangement approach has been successfully applied to develop a novel protocol for the synthesis of the dihydrofuro[2,3-b]benzofuran and furo[2,3-b]benzofuran ring systems.
