摘要
A palladium-catalyzed cascade cyclization and alkynylation of 2-alkynylphenols with bromoalkynes to the synthesis of 3-alkynylbenzofuran scaffolds has been developed. A variety of 3-alkynylbenzofuran derivatives were prepared in good yields under mild conditions. Notably, this protocol was applied to the late-stage modification of bioactive molecule. A palladium-catalyzed cascade cyclization and alkynylation of 2-alkynylphenols with bromoalkynes has been reported. The method provides an efficient tool to construct the 3-alkynylbenzofuran derivatives, as well as late-stage modifies the bioactive molecule. image
