Rearrangements of tricyclic ketones: [3.3.3]propellane formation via a γ-enolate revealed in an approach to the pentalenene skeleton through β-enolization

Article abstract of DOI:10.1139/v94-010

The known isomerization of the tricyclo[5.3.1.0^1,5]- to the [6.3.0.0^1,5]undecane skeleton by β-homoenolization led to examination of 2,9,9-trimethyl-6-methoxymethyltricyclo[5.3.1.0^1,5 ]undecanone (6) as a potential precurs
