The key C10-C26 fragment in a total synthesis of (-)-amphidinolide E has been prepared from an oxolane-containing C10-C17 segment (9, derived from L-glutamic acid) via a Julia-Kocienski reaction with aldehyde 3, followed by a Sharpless AD to obtain the desired diol. The C22-C26 fragment was installed by means of an efficient Suzuki-Molander coupling, with an organotrifluoroborate reagent (4, arising
(-)-两性内酯E的全合成中关键的C10-C26片段是通过含醛环的C10-C17片段(9,衍生自L-谷氨酸)通过与醛3的Julia-Kocienski反应制备的,然后通过Sharpless AD获得所需的二醇。C22-C26片段是通过有效的Suzuki-Molander偶联与有机三氟硼酸酯试剂(4,由乙烯基硼酸酯和2-甲基-1,4-戊二烯之间的交叉复分解反应产生)安装的。
