A divergent synthetic route to (+)-castanospermine 1 and (+)-6-epicastanospermine 2 has been developed via phenylselenoamidation of trichloroacetimidate derived from allylic alcohol 7, and dihydroxylations of trans-olefins 14 and 18 to dispose the three contiguous asymmetric centers, one amino group and two hydroxy groups.
