실험 절차

Following the general procedure for the synthesis of acyloxyalkyl carbamates, D-serine (161 mg, 1.5 mmol) and (2,5-dioxoazolidinyloxycarbonyloxy)methyl 2-methylpropanoate (330 mg, 1.3 mmol) were reacted to provide 110 mg (35% yield) of the title compound (32) as a white powder after work-up and mass-guided preparative HPLC purification. 1H NMR (CDCl3, 400 MHz): δ=6.61 (br s, 1H), 6.51 (d, 1H), 5.65 (m, 2H), 4.41 (m, 1H), 4.02 (m, 1H), 3.84 (m, 1H), 2.59 (m, 1H), 1.09 (d, 6H). MS (ESI) m/z 250.15 (M+H)+; 267.17 (M+NH4)+; 272.13 (M+Na)+; 248.12 (M−H)−.
