| Abstract: | An efficient and stereoselective synthesis of novel furo-pyrano pyrrolidine/pyrrolizidine/indolizidine derivatives has been achieved by intramolecular 3+2] cycloaddition reaction of azomethine ylide generated in situ from O-allyl sugar-derived aldehyde and different secondary amino acids. |
