analogs which are modified at the 5-position (5-O-benzoyl, 5-O-trimethylacetyl, the uronic acid and methyl uronate ester). These nitro sugars were conveniently hydrogenated to the corresponding amino sugars 1A–1E. The utility of the trimethylacetyl protecting group has been demonstrated for this sequence of reactions.
D-木糖已转化为3-硝基-2,3-二脱氧-D-赤藓基呋喃糖苷和几种在5位上修饰的类似物(5-O-苯甲酰基,5-O-三甲基乙酰基,糖醛酸和尿酸甲酯)。这些硝基糖可以方便地氢化为相应的氨基糖1A-1E。已经证明三甲基乙酰基保护基对于该反应序列的效用。
