4. The term spironucleoside was introduced into the bibliography in 1990 (see: Fernández-Bolaños, J.; Blasco López, A.; Fuentes Mota, J. Carbohydr. Res. 1990, 199, 239–242) to designate a class of sugar derivative with spiranic structure, in which the anomeric carbon simultaneously belonged to the sugar ring and to a heterocyclic base. This type of compound had been reported previously but, as far as we are aware, without the use of the term spironucleoside. Since then, this generic term has been widely used and applied to hydantocidin and related compounds. See as examples: (a) Gimisis, T.; Castellari, C.; Chatgilialoglu, C. Chem. Commun. 1997, 2089–2090; (b) Sano, H.; Mio, S.; Kitagawa, J.; Shindou, M.; Honma, T.; Sugai, S. Tetrahedron 1995, 46, 12563–12572; (c) Tronchet, J. M. J.; Kovacs, I.; Barbalat-Rey, F.; Holm, M. V.
