A synthesis of the enantiopure 2-ribosyl-1,4-diazepan-3-one core of liposidomycins, a class of complex lipid nucleoside antibiotics, according to a flexible asymmetric synthesis strategy is described. It involves two building blocks, an enantiopure α-azido-β,γ-epoxybutanol readily available from L-ascorbic acid, and an α-ribosylamino acid obtained from D-ribose. Subsequent cyclization by regiospecific
根据灵活的不对称合成策略,描述了对映体纯 2-ribosyl-1,4-diazepan-3-one 核心 liposidomycins 的合成,这是一类复杂的脂质核苷抗生素。它涉及两个结构单元,一个是从 L-抗坏血酸中容易获得的对映体纯 α-叠氮基-β,γ-环氧丁醇,另一个是从 D-核糖中获得的 α-核糖基氨基酸。随后通过氨基酸对环氧化物的区域特异性亲核打开进行环化,然后进行肽偶联,得到目标核糖基二氮杂环酮。
