FERRAZ, Helena M. C.; SANO, Myrian K.; BOMBONATO, Fernanda I.  and  NUNES, Marta R. S.. Studies on the dehydroiodination of cyclic b-iodo-enol ethers. J. Braz. Chem. Soc. [online]. 2005, vol.16, n.4, pp. 884-887. ISSN 1678-4790.

This work describes the base-promoted dehydroiodination of differently substituted cyclic b-iodo-enol ethers. The products are tetrahydrofuran derivatives bearing two exocyclic double bonds, di- and tetrahydrobenzofurans and a dihydropyran derivative, which were obtained in very good yields.

Keywords : oxygen heterocycles; enol ethers; dihydroiodination.
