A stereocontrolled synthesis of an unsaturated sugar bearing two amino groups (one of them masked as an azide), using an Overman rearrangement as key step, is described. This scaffold is used to prepare two peptides having aromatic fragments, which have shown activity as calpain inhibitors.
描述了使用Overman重排作为关键步骤的立体控制合成的不饱和糖,该不饱和糖带有两个氨基(其中一个被掩盖为叠氮基)。该支架用于制备具有芳族片段的两种肽,它们已显示出作为钙蛋白酶抑制剂的活性。
