2-Bromo-6-hydroxybenzofurans are potentially versatile intermediates for the divergent synthesis of numerous benzofuran-based natural products and their analogues. Herein we report the first one-pot strategy for the efficient synthesis of 2-bromo-6-hydroxybenzofurans. The present protocol provides shorter routes for the synthesis of moracins M, N, O and P; gramniphenols F and G; and morunigrol C using a protecting
