<P><B>Abstract</B></P><P>A concise asymmetric formal synthesis of (–)‐swainsonine from readily available <SMALL>D</SMALL>‐erythronolactone is described. The key steps include a highly diastereoselective amination of a chiral benzylic ether, which occurs with the retention of stereochemistry using chlorosulfonyl isocyanate, and a palladium‐catalyzed decarboxylative <I>N</I>‐allylation of an allyl carbamate.</P>
