that mimic the size, shape, and peripheral functionality of steroidal androgens. In a model system, we used 2D NMR and X-ray crystallographic analysis to show that adjacent N-methyl and oxo substitutents adopt an anti configuration during the coordination reaction. We have synthesized a bis-bidentate oxorhenium(V) complex whose structure and peripheral functionality mimic 5alpha-dihydrotestosterone
我们准备了一系列a双齿状的complex配合物,它们模拟了甾体雄激素的大小,形状和外围功能。在模型系统中,我们使用了2D NMR和X射线晶体学分析,表明相邻的N-甲基和氧代取代基在配位反应过程中采用了反构型。我们已经合成了一个双齿的oxorhenium(V)复合物,其结构和外围功能类似于5alpha-dihydrotestosterone。2D-NMR分析表明,N-甲基和氧代取代基通过与C-18等效的甲基的β-取向而被驱动为甾体抗构型(β-N-甲基,α-氧代)。因此,这种金属络合物提供了类固醇的显着结构和立体化学模拟。然而,其体内稳定性似乎受到限制。
