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.

The N-methyl-1,2-propadiene-1-carboxanilides 6a-h, differently substituted in the p-position, are synthesized by Wittig reaction of the carbamoylmethylenephosphoranes 5 with ketene.They isomerize by thermolysis in boiling xylene to give the tricycles 7a-h, the products of the intramolecular Diels-Alder reaction, and in some cases also to the quinolones 9, the products of a cyclization reaction.The order of the reaction and the influence of the substituents upon the rate of the intramolecular Diels -Alder reaction are determined by 1H-NMR spectroscopy.

The 2,3-butadienanilides 6a-h, unsubstituted in the ω-position, are synthesized by the ynamine way and submitted to thermolysis.They isomerize without exception by intramolecular Diels-Alder reaction more or less quickly, irreversibly, and quantitatively
