Parallel Syntheses of (+)‐ and (−)‐α‐Cuparenone by Radical Combination in Crystalline Solids

Abstract

Photo[Organic]synthesis: Irradiation of well-designed crystalline ketones can result in the solvent-free generation of compounds having adjacent quaternary stereogenic centers, as illustrated for the enantiospecific synthesis of the natural products (+)- and (−)-(α)-cuparenone (see picture).
