New synthetic approaches to the angular and propellane sesquiterpene triquinanes (±)-pentalenene 2 and (±)-modhephene 3, respectively, are described. The syntheses are based on tandem cyclisations involving α-ketene alkyl radical intermediates produced fr
α-ketenyl radical intermediates in the synthesis of propellanes. A formal synthesis of modhephene

, p. 6975 - 6978 (2007/10/03)
A tandem transannulation - cyclisation sequence from a cyclooctenyl substituted α-ketenyl radical intermediate, viz 1, is used as the basis of a new, formal, synthesis of the naturally occurring triquinane modhephene 2.
