A diverse set of isoxazoles, with activity in three different disease categories, was reduced asymmetrically from pro-chiral ketones to chiral alcohols using the Corey-Bakshi-Shibata methodology at the α, β, and γ positions relative to the C-5-methyl of the isoxazole. The experiments described provide an easy route to hydroxylated isoxazoles that represent the common CYP-450 3A4 metabolic site.
使用 Corey-Bakshi-Shibata 方法在相对于 C-5-甲基的 α、β 和 γ 位置,一组不同的异恶唑在三种不同的疾病类别中具有活性,从前手性酮不对称地减少到手性醇异恶唑。所描述的实验为羟基化异恶唑提供了一种简单的途径,代表常见的 CYP-450 3A4 代谢位点。
