Abstract

By employing the appropriate chiral bicyclic lactams, the asymmetric total synthesis of four enantiopure azasugars mentioned in the title were successfully achieved. A series of diastereoselective oxidations (OsO 4NMO) followed by diastereoselective reductions (BH3, 9-BBN) gave good yields of the trisubstituted (16) and tetrasubstituted (2, 3, 4) pyrrolidine and piperidines respectively.
