Observations on the samarium diiodide-promoted C–C fragmentation/ring expansion chemistry of some aliphatic 1,4-diketones
Abstract
Various multicyclic and bridged 1,4-diketones were subjected to the reductive conditions of the SmI2–HMPA system, often affording surprising results and reactivity upon fragmentation of the 2,3 C–C bond to provide the corresponding ring enlarged product.
