products. Stereoselective total synthesis of (+)-anamarine and the first synthesis of 8-epi-(–)-anamarine, its nonnatural diastereomer, were achieved from readily available d-mannitol. The key reactions involved were asymmetric dihydroxylation, cross-metathesis and ring-closing metathesis reactions. The approach is adoptable advantageously for the diversity-oriented synthesis of several related classes
摘要 立体选择性的全合成(+)-橘红和第一个合成的8- Epi -(-)-橘红是其非天然非对映异构体,是从现成的d-甘露醇中获得的。涉及的关键反应是不对称二羟基化,交叉复分解和闭环复分解反应。该方法有利地可用于几种相关类别的天然产物的面向多样性的合成。 立体选择性的全合成(+)-橘红和第一个合成的8- Epi -(-)-橘红是其非天然非对映异构体,是从现成的d-甘露醇中获得的。涉及的关键反应是不对称二羟基化,交叉复分解和闭环复分解反应。该方法有利地可用于几种相关类别的天然产物的面向多样性的合成。
