respectively) and vancomycin-resistant Enterococcus faecalis (VRE). Described herein is the first totalsynthesis of both enantiomers of this bisanthraquinone antibiotic, the determination of its absolute configuration, and the biological evaluation of these and related compounds. The developed synthesis relies on a highly efficient cascade sequence involving an intermolecular Diels-Alder reaction between
