The enantioselective synthesis of a new and extremely effective organoselenium reagent (2) is reported. This chiral reagent was found to react with alkenes with a very high degree of facial selectivity in selenomethoxylation and ring closure reactions. In some cases the diastereoselectivities were found to be as high as 98%.
