A selective intramolecular 5-exo-dig or 6-endo-dig cyclization en route to 2-furanone or 2-pyrone containing tricyclic scaffolds.


ABSTRACT: Ringfused bicyclic 2-pyridones exhibit interesting biological properties against pili assembly in uropathogenic Escherichia coli (Pinkner, J. S. et al. Proc. Natl. Acad. Sci. U. S. A.2006, 103, 17897-17902; Åberg, V. et al. Org. Biomol. Chem.2007, 5, 1827-1834) as well as curli formation (Cegelski, L. et al. Nat. Chem. Biol.2009, 5, 913-919). In the search for new ring-fused central fragments, highly selective synthetic routes to the 2-furanone or 2-pyrone containing tricyclic scaffolds 1 and 2 have been developed.
