A concise stereoselectivesynthesis of (+)-1-deoxy-6-epi-castanospermine has been developed through stereoselective approach from the chiral precursor R-Glycidol. The key steps in the synthesis involve Grignard reaction through Weinreb amide, followed by Sharpless dihydroxylation and stereoselective reduction of imine assigned the required stereochemical feature of indolizidine azasugar (+)-1-deox
