formal synthesis of (+)-pyrenolide D from (E)-crotonaldehyde is described. The key steps include an enantioselective Sharpless dihydroxylation of protected hex-4-en-1-yn-3-ol and a highly diastereoselective palladium-catalysed oxycarbonylation of (2R,3S,4S)-hex-5-ene-2,3,4-triol using iron pentacarbonyl as the carbon monoxide source. A concise, asymmetric formal synthesis of (+)-pyrenolide D from (E)-crotonaldehyde
摘要 描述了由(E)-巴豆醛的(+)-吡咯内酯D的简明,不对称形式合成。关键步骤包括受保护的hex-4-en-1-yn-3-ol的对映选择性Sharpless二羟基化和(2 R,3 S,4 S)-hex-5-ene-2的高非对映选择性钯催化的氧羰基化,3,4-三醇用五羰基铁作为一氧化碳源。 描述了由(E)-巴豆醛的(+)-吡咯内酯D的简明,不对称形式合成。关键步骤包括受保护的hex-4-en-1-yn-3-ol的对映选择性Sharpless二羟基化和(2 R,3 S,4 S)-hex-5-ene-2的高非对映选择性钯催化的氧羰基化,3,4-三醇用五羰基铁作为一氧化碳源。
