A. Fernandezmateos et al., MODEL INSECT ANTIFEEDANTS - SYNTHESIS OF AZADIRADIONE FRAGMENTS THROUGH ACYL RADICALS CYCLIZATIONS AND STANNANE COUPLING REACTIONS, Tetrahedron, 52(13), 1996, pp. 4817-4828
A diastereoselective and versatile synthesis of the model insect antif
eedant 16 related to azadiradione has been achieved in nine steps star
ting from alpha-cyclocitral 1. The key steps involve intramolecular al
kene addition of an acyl radical and a Stille coupling reaction of a v
inyl iodide with a stannylfuran.
