실험 절차

Following the general procedure for the synthesis of acyloxyalkyl carbamates, D-serine (504 mg, 4.8 mmol) and (2,5-dioxoazolidinyloxycarbonyloxy)ethyl 2,2-dimethylpropanoate (1.1 g, 4.0 mmol) were reacted to provide 305 mg (28% yield) of the title compound (24) as a white powder after work-up and mass-guided preparative HPLC purification. 1H NMR (CDCl3, 400 MHz): δ=6.78 (m, 1H), 6.40 (br s, 1H), 6.11 (t, 1H), 4.41 (m, 1H), 4.04 (m, 1H), 3.93 (m, 1H), 1.44 (2d, 3H), 1.20 (s, 9H). MS (ESI) m/z 278.05 (M+H)+; 295.06 (M+NH4)+; 300.04 (M+Na)+; 276.04 (M−H)−.
