The radical decarboxylation of β- and γ-amino acids on treatment with PhI(OAc)2a-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.

A cobalt-catalyzed cross-coupling between alkyl iodides and cyclopropyl, cyclobutyl, and alkenyl Grignard reagents is disclosed. The reaction allows the introduction of strained rings on a large panel of primary and secondary alkyl iodides. The catalytic system is simple and nonexpensive, and the reaction is general, chemoselective, and diastereoconvergent. The alkene resulting from the cross-coupling can be transformed to substituted cyclopropanes using a Simmons-Smith reaction. The formation of radical intermediates during the coupling is hypothesized.
Iron- and cobalt-catalyzed arylation of azetidines, pyrrolidines, and piperidines with grignard reagents

supporting information, p. 6160 - 6163 (2015/01/16)
Iron- and cobalt-catalyzed cross-couplings between iodo-azetidines, -pyrrolidines, -piperidines, and Grignard reagents are disclosed. The reaction is efficient, cheap, chemoselective and tolerates a large variety of (hetero)aryl Grignard reagents.
