A Radical Access to Highly Functionalized Tetrahydroxanthones. Issue 33 (4th July 2013) - Meister, Anne C.
Abstract Center stage: A radical synthesis of highly functionalized tetrahydroxanthones is presented. The key step, the build‐up of the quarternary stereocenter, is performed through a diastereoselective intramolecular radical Michael addition (see scheme). This offers versatile access to three different precursors for natural products.
