A new method for the synthesis of fused and bridged ringsystems based on intramolecular addition of a vinyl radical to α,β-unsaturated carbonyls is described. The method represents a general route to masked γ-diketones.
The first examples of selective additions of organosilicon radicals are reported. Trichlorosilyl radicals preferentially attack the carbonyl oxygen atom, while triethylsilyl radicals preferentially attack alkenes. Carbon-carbon bond formation to produce both monocyclic and bridged bicyclic systems is possible.
