Reaktionsschritte

To 20 mL of methanol was slowly added 2.6 mL acetyl chloride. Then 2.0 g (17.1 mmole) of L-norvaline was added. The solution was heated to reflux and monitored by thin-layer chromatography (TLC) until complete. The methanol was stripped off by rotary evaporation and the resulting oil was pumped under high vacuum overnight to give the title compound. NMR(300 MHZ, CD3OD): δ 4.03 (t, Nva-α, 1H), 3.81 (s, COOCH3, 3H), 1.87 (m, CH2CH2CH3, 2H), 1.44 (m, CH2CH2CH3, 2H), 0.98 (t, CH2CH2CH3, 3H).
