Spiroepoxy naphthalenones, obtained from the stereoselcctive oxidation of 2-hydroxyalkyl-1-naphthols with sodium periodate, were converted to naphthalene-1,2-oxides by reaction with methyllithium followed by Payne rearrangement.
Synthesis of Fused Aromatic [1,3]Dioxoles from 2-Hydroxymethylphenols
The rearrangement of spiroepoxycyclohexadienones to benzo[1,3]dioxoles is best carried out in a non polar solvent (toluene, CCl4) in presence of TBDMSCl. Application to the synthesis of naphthalene and tetrahydronaphthalene derivatives is described.

Feedstock aromatic compounds are compelling low-cost starting points from which molecular complexity can be generated rapidly via oxidative dearomatization. Oxidative dearomatizations commonly rely heavily on hypervalent iodine or heavy metals to provide the requisite thermodynamic driving force for overcoming aromaticstabilizationenergy. This article describes oxidative dearomatizations of 2-(h
