  Aldehyde–alkene cyclizations via O-stannyl ketyl radicals using sugars as chiral auxiliaries

  摘要：

  This investigation illustrates the utility of two inexpensive carbohydrate derivatives as sources of asymmetry for aldehyde-alkene radical cyclizations. Diastereomeric ratios as high as 9:1 were achieved with an ester-appended (+)-isosorbide and 100:1 for (+)-isomannide. Temperature dependence, Lewis acids and solvents were all examined.
