title: Structural revision of epoxyrollins A and B, biosynthetic precursors of annonaceous acetogenins.
abstract: Chemical structural elucidation of epoxyrollins A and B, representatives of biosynthetic precursors of tetrahydrofuran and tetrahydropyran annonaceous acetogenins, is described. These chemical structures were diepoxyreticanin 1 (4) and diepoxymuricanin A (6) by a (13)C-NMR and mass spectral study of the natural and synthetic sample data.
