The syntheses of methyl 2,3-diamino-4,6-O-benzylidene-2,3-dideoxy-α-d-hexopyranosides of glucose, mannose, gulose, and talose and methyl 2-amino-4,6-benzylidene-2,3-dideoxy-3-tosylamido-α-d-glucopyranoside are exhaustively presented, as well as their application as ligands in half-sandwich ruthenium(II), rhodium(III), and iridium(III) complexes. The complex formation occurs highly diastereoselectively
甲基的合成2,3-二氨基-4,6- ø -亚苄基-2,3-二脱氧α- d葡萄糖,甘露糖,古洛糖,塔罗糖和和甲基-hexopyranosides 2-氨基-4,6-苯亚甲基2,3-二脱氧-3-甲苯磺酰基-α- d-葡萄糖吡喃糖苷被详尽介绍,以及它们作为半三明治钌(II),铑(III)和铱(III)配合物中的配体应用。络合物的形成是高度非对映选择性的,从而产生了立体金属中心。配体及其配合物的分子结构通过X射线结构分析,NMR光谱,极化法和DFT方法进行了研究。二氨基单糖复合物已经进行了抗肿瘤活性研究。几种钌配合物针对不同癌细胞类型的体外测试显示,其抗增殖活性比顺铂低4-10倍。
