Name:
Haworth Phenanthrene Synthesis
Detailed information:
Acylation of aromatic compounds with aliphatic dibasic acid anhydrides to β-aroylpropionic acids, reduction of the carbonyl group according to Clemmensen or Wolff-Kishner procedures, cyclization of the γ-arylbutyric acid with 85% sulfuric acid, and conversion of the cyclic ketone to polycyclic hydroaromatic and subsequently to aromatic compounds.
