反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A suspension of the product from step (c) (1.3 g) and 10% w/w Pd/C (1.0 g) in 30% w/w ethanolic dimethylamine (25 ml) was hydrogenated for 24 hours and filtered through Hyflo. Fresh Pd/C (0.7 g) and ethanolic dimethylamine (5 ml) were added to the filtrate and hydrogenation continued for a further 16 hours. The mixture was filtered through a silica column using DCM/EtOH/NH4OH (40:8:1) as eluant to give the desired product as a colourless foam (0.3 g). Elemental analysis and 1H NMR were consistent with the proposed structure. filtered through Hyflo Fresh Pd/C (0.7 g) and ethanolic dimethylamine (5 ml) were added to the filtrate and hydrogenation continued for a further 16 hours The mixture was filtered through a silica column

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of the product from step (b) (2.5 g) and polyphosphate ester (20.0 g) in chloroform (40 ml) was refluxed for 20 minutes. Ice was added to the cooled mixture and the chloroform evaporated in vacuo. The remaining aqueous phase was extracted with ethyl acetate and the combined extracts evaporated in vacuo to give the desired product as a pale yellow oil (1.8 g). Ice was added to the cooled mixture the chloroform evaporated in vacuo The remaining aqueous phase was extracted with ethyl acetate the combined extracts evaporated in vacuo
