  systems are commonly undertaken through cyclization and cycloaddition reactions, but the formation of seven- and eight-membered-ring systems are not as abundant. An efficient and high-yielding method for the synthesis of seven- and eight-membered-ring nitrogen-containing heterocycles by ring-closing metathesis is reported. uracil - azepine - azocine - ring-closing metathesis

  Novel pyrrolo[3,2-d]pyrimidine derivatives have been synthesized by an efficient and regioselective Fe (III)-mediated iodocyclization method starting from a commercially available uracil compound. Here, iron has a dual role in the iodocyclization process by acting as a Lewis acid which promotes the release of I+ cation from iodine by removing iodide ion, and also as an oxidant which again generates

  日期：——

  Synthesis of a series of five-membered sultams containing different hetero- or carbocycles were obtained in good to excellent yields by ring-closing metathesis (RCM) reaction. Many sultams were precipitated from the reaction mixture and they were easily separated by filtration without further purification.
