  Samarium(II) iodide mediated intramolecular reductive coupling of carbonyl groups and alkynes in the presence of HMPA and t-BuOH was successfully performed to provide cyclized products. Some cyclic compounds containing a heteroatom such as oxygen or nitrogen were also efficiently prepared by this coupling reaction.
