constituents of most anthracycline antitumour antibiotics. For an investigation of structure-activity relationships, the four diastereomeric amino sugars daunosamine, acosamine, ristosamine, and epi-daunosamine were synthesised in short and efficient routes starting from commercially available rhamnose. Several glycosyl donors were provided and their use was exemplified in the synthesis of acosaminyl-e
3-氨基-2,3,6-三甲氧基己基吡喃糖是大多数蒽环类抗肿瘤抗生素的重要组成部分。为了研究结构-活性关系,从市售鼠李糖开始以短而有效的途径合成了四种非对映体氨基糖柔红胺,二十二胺,香豆胺和表柔红胺。提供了几种糖基供体,其用途在合成氨糖基-ε-异二十四烯酮中得到了例证。
