Abstract

Einladung zum T: Erstmals wurde der T‐förmige Bisanthrachinon‐Naturstoff BE‐43472B durch Totalsynthese hergestellt und seine Absolutkonfiguration aufgeklärt. Wesentliche Schritte der zentralen Kaskadensequenz sind eine Diels‐Alder‐Reaktion, die Bildung eines Halbketals und eine nucleophile aromatische ipso‐Substitution.
