The totalsynthesis and determination of the absolute configuration are described for paraconiothin I, an inhibitor against the nuclear receptor liver X receptor α, which is produced by the endophytic fungus Paraconiothyrium brasiliense ECN258. Our method for synthesizing paraconiothin I involved Evans asymmetric alkylation and Sharpless asymmetric dihydroxylation, which enabled us to develop an efficient
描述了 paraconiothin I的全合成和绝对构型测定,paraconiothin I 是一种针对核受体肝 X 受体 α 的抑制剂,由内生真菌Paraconiothyrium brasiliense ECN258 产生。我们合成副葱素 I 的方法涉及 Evans 不对称烷基化和 Sharpless 不对称二羟基化,这使我们能够开发出一种有效的合成方法来构建副葱素 I 的侧链部分。通过模型合成,我们发现先前提出的天然产物的相对构型产品不正确,并通过比较合成产物和天然产物的比旋光度确定了天然产物的正确绝对构型。
