Versuchsvorschrift

To a solution of 6-hydroxy-5-nitro-1-tetralone (0.888 g, 4.29 mmol) in dry THF (10 mL) was added (R)-1-imidazol-1-ylmethyl-2-methyl-propanol (0.737 g, 4.78 mmol) followed by triphenylphospine (1.26 g, 4.78 mmol). After approximately 10 min, diethylazodicarboxylate (0.75 mL, 4.78 mmol) was added slowly. The reaction was allowed to stir at RT for 2 days. The reaction mixture was concentrated under reduced pressure and the residue was purified by chromatography (SiO2, 20% acetone/CH2Cl2 then 5% MeOH/CH2Cl2) afforded the title compound as a foam (1.02 g, 2.97 mmol, 69%). The structure was confirmed by NMR and mass spectrometry. MS m/z 344 (M++H). 2. 5-Amino-6-((S)-1-imidazol-1-ylmethyl-2-methyl-propoxy)-3,4-dihydro-2H-naphthalen-1-one
