Fecha de publicación: | 24-ago-2005 | Editor: | Elsevier | Citación: | Tetrahedron 61(40): 9550-9554 (2005) | Resumen: | Three naturally occurring pyranosyl-like polyhalogenated metabolites 1–3 as well as their likely biogenetic precursor, the linear compound 4, have been isolated from the red alga Ptilonia magellanica. They are the first compounds within the genus that incorporate chlorine in their network. Compound 3 have structural features reminiscent of the universal chemical signal AI-2 (autoinducer-2) for bacterial communication. This work was supported by the Ministerio de Educación y Ciencia (PPQ2002-02494, REN2002-10485-E/ANT), and the Gobierno de Canarias DGUI (PI2002/044).
