Abstract
A method for the synthesis of bis-tetrahydrofuranyl annonaceous acetogenins, including the natural products and analogs thereof, is provided which proceeds by the Pd-mediated coupling of a bis-tetrahydrofuranyl-subunit comprising a terminal alkyne, with a (C4)-hydroxybutenolide subunit comprising a terminal vinyl iodide, followed by selective reduction of the resulting enyne.
