, p. 754 - 758 (2018)
A palladium(0)-catalyzed ring-opening cross-coupling reaction between tert -cyclobutenols and aryl halides produces γ-arylated β,γ-unsaturated ketones. In the case of aryl halides bearing functional groups at the ortho position, the resulting ring-opened ketones undergo intramolecular condensation to afford bicyclic aromatic compounds.

A palladium-catalyzed intramolecular α-arylation and defluorinative aromatization strategy for the synthesis of polysubstituted 2-naphthols is reported. With ortho-bromobenzyl-substituted α-fluoroketones as the substrates and palladium acetate/triphenylphosphine as the catalyst, this method features good functional group tolerance, readily available catalyst and starting materials, and high yields. The applications of the strategy are demonstrated by the synthesis of useful building blocks, such as naphtha[2,3-b]furan, naphthol AS-D, and ligands/catalysts. (Figure presented.).

A novel method for the generation of o-quinodimethane (o-QDM) intermediates is reported using a mild and efficient base-promoted ring-opening of benzo[c]oxepines. Among the benzo[c]oxepines studied, indanone containing analogues demonstrated the greatest
