An expedient stereoselective total synthesis of 18-carbon (+)-(6S,9R,10R)-bovidic acid, isolated from the pelage and skin of a gaur B. frontalis is described using l-proline catalysed sequential α-aminoxylation and Horner–Wadsworth–Emmons olefination of aldehyde, cross metathesis and tandem Sharpless asymmetric dihydroxylation-SN2 cyclization reaction as the key steps.
从gaur B.的额叶和皮肤中分离出的18-碳(+)-(6 S,9 R,10 R)-硼酸的立体选择性全合成方法,使用l-脯氨酸催化的顺序α-氨基木糖基化方法描述了额叶。和Horner–Wadsworth–Emmons醛的烯化,交叉复分解和串联Sharpless不对称二羟基化-S N 2环化反应是关键步骤。
