The first total synthesis of brevisamide (1) has been accomplished in 21 linear steps starting from cis-but-2-ene-1,4-diol. A synthetic highlight is the Suzuki−Miyaura coupling between an ether ring fragment and a dienol side chain. This result confirmed the structure of 1 isolated from the dinoflagellate Karenia brevis.
从顺式-丁-2-烯-1,4-二醇开始,在21个线性步骤中完成了短酰胺( 1 )的第一次全合成。合成亮点是醚环片段和二烯醇侧链之间的 Suzuki-Miyaura 偶联。该结果证实了从短鞭毛藻Karenia brevis中分离的1的结构。
