Strategies with Iodine in Synthesis Abstract A facile and efficient method for the syntheses of N-substituted 2-amino-3,4-diiodofurans from various readily available allenic amides has been developed. The reaction was postulated to proceed via an NIS-mediated electrophilic iodocyclization pathway. A facile and efficient method for the syntheses of N-substituted 2-amino-3,4-diiodofurans from various readily available
the head-to-head cyclodimerization products, bismethylenecyclobutanes, as single isomers in good to fair yields. We also carried out the stoichiometric reaction of these allenes in the presence of Ni(0) complexes and elucidated the mechanism of this highly selective reaction.
