A highly diastereoselective synthesis of N-acetylneuraminicacid 1 has been completed by stereoselective functionalization of cis-olefin 6 and trans-olefin 10 via intramolecular phenylselenoamidation and osmylation, respectively.

(+)-7-Deoxy-6-epicastanospermine 1, (−)-7,8-dideoxy-6-epicastanospermine 2 and (−)-N-acetylslaframine 4 have been synthesized via the stereoselective intramolecular iodocyclization of trichloroacetimidates generated from cis-olefinic allylicalcohols 7 and 15, respectively.
