Abstract
The bisanthraquinone antibiotic BE-43472B [(+)-1] was isolated by Rowley and co-workers from a streptomycete strain found in a blue-green algae associated with the ascidian Ecteinascidia turbinata and has shown promising antibacterial activity against clinically derived isolates of methicillin-susceptible, methicillin-resistant, and tetracyclin-resistant Staphylococcus aureus (MSSA, MRSA, and TRSA, respectively) and vancomycin-resistant Enterococcus faecalis (VRE). Described herein is the first total synthesis 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 diene (R)-61 and dienophile 55, followed by an intramolecular nucleophilic aromatic ipso substitution. Late-stage transformations included a remarkable photochemical alpha,beta-epoxyketone rearrangement [80 --> (+)-1]. Interestingly, the unnatural enantiomer [(-)-1] of antibiotic BE-43472B exhibited antibacterial properties comparable to those of the natural enantiomer [(+)-1].

Abstract
The growing importance of cascade reactions reflects and imparts advances in the state of the art of organic synthesis and underscores the desire of synthetic chemists to achieve higher levels of elegance and efficiency. Besides their esthetic appeal, cascade processes offer economical and environmentally friendly means for generating molecular complexity. Because of their many advantages, these reactions have found numerous applications in the synthesis of complex molecules, both natural and designed. In this tutorial review, we highlight the design and execution of cascade reactions within the context of total synthesis as demonstrated with selected examples from these laboratories.
