  名称：

  Studies on the diastereoselectivity of samarium(II) iodide mediated reductive carbocyclizations of ω-iodo-α,β-unsaturated esters prepared from 2-deoxy-d-ribose

  摘要：

  The title compounds were reduced with SmI2 or Bu3SnH to give carbocyclic compounds in good yield. The stereoselectivity of the SmI2 reductive carbocyclizations varies with the reaction conditions, the double bond geometry and with the identity of the hydroxyl protecting groups. Keywords: Alkenyl halides, carbohydrates, cyclisation, samarium and compounds.

  omega-Iodo-alpha,beta-unsaturated esters were reduced with SmI2 or Bu3SnH under different conditions to give carbocyclic compounds in good yield. The stereoselectivity of the SmI2 cyclizations varies with the choice of promoter, the reaction temperature, the identity of the hydroxyl protecting groups and the geometry of the double bond.
