  A short, enantioselective synthesis of 6,7-diepicastanospermine (4) has been achieved by an intramolecular azide-diene 1,3-dipolar cycloaddition, followed by ring-opening of the vinylaziridine 6 and subsequent dihydroxylation.

  The polyhydroxylated indolizidines castanospermine and swainsonine as well as some of their stereoisomers are powerful glycosidase inhibitors. An efficient and stereochemically flexible synthesis of racemic 1,7,8-trihydroxylated and 1,6,7,8-tetrahydroxylated indolizidines (castanospermine stereoisomers) from readily available N-substituted gamma-oxygenated alpha,beta-unsaturated sulfones 3 and 4 has been developed. The construction of the bicyclic skeleton of 1-hydroxyindolizidine has been accomplished by intramolecular conjugate addition of the nitrogen moiety of 3 and 4 to the alpha,beta-unsaturated sulfone unit to give the pyrrolidine intermediates 5 and 6, followed by formation of the C(7)-C(8) bond by intramolecular acylation (or alkylation) of the alpha-sulfonyl carbanion. The stereoselectivity of the pyrrolidine synthesis was highly dependent on the bulkiness of the gamma-oxygenated function; thus, the free alcohols gave predominantly cis-pyrrolidines while the OTIPS derivatives led to the trans isomers. After straightforward functional group transformations, the removal of the sulfonyl group at C(8) either by Julia reaction or by basic elimination (depending on the substrate used) afforded the key C(7)C(8) unsaturated indolizidines 10, 22, 30, and 31, whose stereoselective dihydroxylations with OsO4 gave a variety of cis C(1)C(8a) and-trans C(1)C(8a) trihydroxylated and tetrahydroxylated indolizidines, among which (+/-)-1,7-di-epi-castanospermine and (+/-)-1,8-di-epi-castanospermine have been reported for the first time.
