摘要

Important goals for such investigations are the development of synthetic equivalents for the alanine@-cation 1 and the alanine@-anion 2. There are several approaches to the synthon 1, including 3-iodo-and 3-(tosyloxy) alanhe derivatives 3a and 3b, 4 the &lactone 4, 5 the aziridine 5: and the sulfamidate 6,'all of which are derived from serine. In addition, an indirect approach using the D-mannitolderived bis (aziridine) 7 has also been explored? ...
