castanospermine analogues incorporating a stereoelectronically anchored axial hydroxy group at the pseudoanomeric stereocenter (C-5) have been synthesized to satisfy the need for glucosidase inhibitors that are highly selective for alpha-glucosidases. The polyhydroxylated bicyclic system was built from readily available hexofuranose derivatives through a synthetic scheme that involved (i) the construction
合成了一系列在缩氨基立体中心(C-5)上结合了立体电子锚定轴向羟基的氨基缩酮栗精胺类似物,以满足对α-葡糖苷酶具有高度选择性的葡糖苷酶抑制剂的需求。多羟基化的双环体系是由合成后的方案由现成的六呋喃糖衍生物构建而成,该方案涉及(i)在非还原端构建五元环状(硫代)氨基甲酸酯或(硫代)脲部分,以及(ii)分子内亲核加成硫代氨基甲酸酯氮原子与单糖的掩蔽醛基的关系。报道了针对几种糖苷酶的还原性2-氧杂-和2-氮杂吲哚并核苷的生物学筛选。
