paper describes the total synthesis of the hydrochloride salts of (2S)-2-amino-7-methoxytetralin (21-HCl) and (2S)-2-amino-6-fluoro-7-methoxytetralin (ST1214), from a common enantiomerically pure aziridine 4b, which was available from l-aspartic acid β-tert-butyl ester. The synthesis of 21-HCl and ST1214 proceeded in nine steps and 5 and 6% overall yields, respectively. Key steps are the regioselective
