Manganese(III) acetate and cerium(IV) ammonium nitrate were the reagents of choice for the oxidative generation of radicals, whereas samarium(II) iodide was employed for reductive couplings. Both strategies were realized by using easily available starting materials, with acetic acid as C-2 and ethyl acrylate as C-3 building blocks, respectively Y1 - 2005 SN - 0039-7881 ER - TY - JOUR A1 - Peters, Karl A1 - Peters, E.
