Abstract |
A cascade sequence featuring a Diels-Alder reaction, a lactolization, and an SN(Ar)-type substitution forms the core of the bisanthraquinone antibiotic BE-43472B in its first total synthesis, which K. C. Nicolaou et al. describe in their Communication on page 3444 ff. The background of the cover picture is a photograph of Ecteinascidia turbinata (courtesy of John Easley Photography), the marine source of the streptomyces strain producing this antibiotic. |
