The first total synthesis of (−)-mucosin (6), an unusual marine hydrindane natural product incorporating a prostaglandin-like submotif, has been achieved. As a result of the campaign, three of the four all-carbon stereocenters in the purported structure 1 have been revised. Of particular note is the excellent control over β-chirality in conjugate addition to ester (−)-22 and the facial selectivity
已经实现了(-)-粘膜素(6)的第一个全合成,这是一种不寻常的海洋氢化天然产物,并掺入了类似前列腺素的亚基。这项运动的结果是,据称结构1中的四个全碳立体中心中的三个已被修改。特别值得注意的是,对酯(-)- 22的共轭物加成中的β-手性有极好的控制,并且在随后的中间甲硅烷基乙烯酮缩醛质子化中具有面部选择性。
