Dimeric Naphthoquinones, VII. - Synthesis of Rotundiquinone and 2,3′-Bijuglone via Halogenated BinaphthyldiquinonesAn improved synthesis of the unsymmetric quinoid-quinoid cross-linked [2,3′-binaphthyl]diquinones rotundiquinone (3a) and 2,3′-bijuglone (3c) was achieved by demethylation followed by hydrogenolytic dehalogenation starting from the monobromo derivatives 14a and 14c. Synthesis and properties of some more halogenated bijuglones are described.
Notes:
Eine verbesserte Synthese der unsymmetrisch über die chinoiden Ringe verknüpften [2,3′-Binaphthyl]dichinone Rotundichinon (3a) und 2,3′-Bijuglon (3c) geht von den leicht zugänglichen Monobromderivaten 14a und 14c aus, die sich glatt entmethylieren und anschließend hydrogenolytisch enthalogenieren lassen. Synthesen und Eigenschaften weiterer halogenierter Bijuglone werden beschrieben.
