A New Modulated Oxidative Ring Cleavage of α-Nitrocycloalkanones by Oxone®: Synthesis of α,ω-Dicarboxylic Acids and α,ω-Dicarboxylic Acid Monomethyl Esters

By the appropriate choice of the reaction conditions Oxone® produces the ring cleavage of α-nitrocycloalkanones affording good yields of α,ω-dicarboxylic acids and α,ω-dicarboxylic acid monomethyl esters, respectively, regardless the ring size and/or the presence of an alkyl group as substituent.
