Synthesis of functionalized nitrogen heterocycles from β- and γ-amino acids by radical decarboxylation

The radical decarboxylation of β- and γ-amino acids on treatment with PhI(OAc)2–I2 is a mild and efficient methodology to synthesize halogenated or oxygenated nitrogen heterocycles. The reaction was applied to the synthesis of bioactive products, such as opioid analogues, iminosugars and new antifungic agents.
