A New Method for the Synthesis of 2,3-Aziridino-2,3dideoxyhexonamides and Their Conversion into 3-Amino-2,3dideoxyhexenoic Acids.-New 2,3-aziridino-2,3-dideoxyhexonamides (VII) and (IX) can be prepared from the lactones (I) and (VIII) via treatment of the mesylates with aqueous ammonia. The diastereomerically pure carboxamides are precursors for 3-amino-2,3-dideoxyhexenoic acids. -(JOERGENSEN, C.; PEDERSEN, C.; SOETOFTE, I.; Synthesis (1998) 3, 325-328; Dep. Org. Chem., Tech. Univ.
