Studies on the Chemistry of 2-(2-Oxo-3-phenylpropyl)-benzaldehydes: Novel
Total Synthesis of 3-Phenylnaphthalen-2-ols and 2-Hydroxy-3-phenyl-1,4-naphthoquinones. — The title aldehydes (VI) undergo intramolecular aldol condensation
under basic conditions to give naphthols (VII). Oxidation of the latter compounds results in a novel, efficient synthesis of 1,2-naphthoquinones (VIII), which are efficiently
transformed into 1,4-naphthoquinones (IX). In addition, treatment of aldehyde (VIa)
under Jones conditions affords acid (X) and isochromenone (XI). It is demonstrated,
that (XI) is formed from (X) by dehydration. — (MARTINEZ, A.; FERNANDEZ, M.;
