An O-stannyl ketyl ring scission–cyclization of a rigid tricyclo [3.3.0.02,8]octan-3-one ring system bearing an alkene tether results in the synthesis of a linear triquinane skeleton.

alpha-ketocyclopropane via O-stannylketyls. A preference for cleavage of the cyclopropane bond with the best orbital overlap with the ketyl radical sp(2)-orbital even in the presence of radical stabilizing groups is indicated by these results. An O-stannylketyl ring scission-cyclization resulted in the novel synthesis of either a linear or an angulartriquinaneskeleton depending on the length and
