A versatile synthetic route to indolizidines, (+)-7-deoxy-6- epicastanospermine, (-)-7,8-dideoxy-6-epicastanospermine and (-)-N- acetylslaframine

(+)-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 allylic alcohols 7 a
