WebShare your videos with friends, family, and the world WebA new, stereoselective, palladium-catalyzed method for the synthesis of substituted tetrahydrofurans from γ-hydroxy alkenes and aryl bromides forms both a C-C and a C-O bond with diastereoselectivities of up to >20:1. The reactions probably proceed via the intramolecular insertion of an olefin into a Pd (Ar) (OR) intermediate.
