(+)-Swainsonine 2 and (-)-8,8a-di-epi-swainsonine 3 were stereoselectively synthesized from L-glutamic acid via a highly diastereoselective intramolecular conjugate addition of amide 20 and carbamate 8, respectively. Another key step is a stereoselective osmium-catalyzed dihydroxylation of indolizidine double bond.
