  Sequential radical cyclization/intermolecular carbonyl addition reactions initiated by samarium(II) iodide

  摘要：

  A sequential reductive coupling process promoted by samarium (II) iodide (SmI2) is described. Thus, ethyl 2-acetyl-2-methyl-5-hexenoate, upon treatment with SmI2 in the presence of a variety of aldehydes or ketones, undergoes an initial radical (ketyl) olefin cyclization. Subsequent reduction of the intermediate radical generated in this process produces a transient organosamarium species which can be trapped in situ by the added aldehyde or ketone electrophiles. Through this sequential radical cyclization/intermolecular carbonyl addition reaction, two new carbon-carbon bonds are generated in a one-pot process. Furthermore, a high degree of stereochemical control is established over three contiguous stereocenters, markedly increasing molecular complexity from the starting materials to the observed products.
