实验步骤: (1R,2S,3R,4R)-2,3-Dihydroxy-4-(hydroxylmethyl)-1-aminocyclopentan hydro-chloride (70.0 g, 380 mmol) was dissolved in water (660 ml) and FmocOSU (N-(9-Fluorenylmethoxycarbonyloxy)-succinimid) (148.5 g, 440 mmol) solved in dioxan (2.00 l) was added. Then saturated sodium hydrogencarbonate solution (800 ml, 880 mmol) was added slowly. The mixture was stirred 3 h at room temperature until TLC (Silicagel Merck 60, chloroform/methanol/acetic acid 8:2+0.1% v/v/v) showed complete consumption of the educts. The obtained precipitate was filtered off and the filtrate was added to water (6.00 l). The resulting suspension was stirred for 5 min and then stored 12 h at 4° C. The resulting suspension was filtered. The obtained solid was washed with cold water (3.00 l) and dried 12 h under reduced pressure at 45° C. over calcium chloride. For a further purification the crude product was suspended in ethylacetate, stirred 1 h, filtered and dried under reduced pressure yielding 134 g (95%) of the title compound as white solid. was added consumption of the educts The obtained precipitate was filtered off the filtrate was added to water (6.00 l) stored 12 h at 4° C The resulting suspension was filtered The obtained solid was washed with cold water (3.00 l) dried 12 h under reduced pressure at 45° C. over calcium chloride For a further purification the crude product stirred 1 h filtered dried under reduced pressure
