A serendipitous discovery of some intra-molecular enolate addition reactions following a SmI2-mediated reductive cross-coupling between imides and electron-deficient olefins leading to some novel compounds was investigated to determine the generality

Publikováno v: Taaning, R H, Thim, L, Karaffa, J, Campaña, A G, Hansen, A-M, Skrydstrup, T & Taaning, R H 2008, ' SmI2-promoted intra-and intermolecular C-C bond formation with chiral N-acyl oxazolidinones ', Tetrahedron, vol. 64, no. 52, pp. 11884-11895 .

The suitability of chiral oxazolidinones in the SmI2-mediated C-C bond generation between the imide functionality of an N-acyl oxazolidinone unit and an olefinic radical acceptor, in both inter- and intramolecular reactions, was investigated. It was

Publikováno v: Jensen, C M, Lindsay, K B, Taaning, R H, Karaffa, J, Hansen, A M, Skrydstrup, T & Taaning, R H 2005, ' Can decarbonylation of acyl radicals be overcome in radical addition reactions? En route to a solution employing N-acyl oxazolidinones and SmI2/H2O ', Journal of the American Chemical Society, vol. 127, no. 18, pp. 6544-5 . https://doi.org/10.1021/ja050420u

The application of acyl radicals in radical addition reactions in the absence of a CO atmosphere is generally limited to aryl or alpha-unsubstituted alkyl acyl radicals due to competing decarbonylations where the rate constant for this degradation pr
