The structural assignment of each of five sugar components from a basic antibiotic, sporaviridin, is described : two are neutral monosacharides, D-quinovose and D-glucose, and the remaining three are amino sugars, D-viosamine, D-acosamine and L-vancosamine. D-Acosamine is only the second example of a 3-amino-2, 3, 6-trideoxyhexose having D-configuration to be isolated from nature (D-angolosamine was the first).
本文介绍了一种碱性抗生素--孢子丝菌素--中五种糖成分的结构分配:其中两种是中性单水苏糖,即 D-奎诺瓦糖和 D-葡萄糖,其余三种是氨基糖,即 D-维奥沙明、D-阿可沙明和 L-万古沙明。D-氨基葡糖是第二个从自然界分离出的具有 D-构型的 3-氨基-2,3,6-三脱氧己糖的例子(第一个是 D-甘露糖胺)。
