enantiodivergence was uncovered as a new phenomenon in the biosynthesis of natural products. In nature, chiral natural products are usually produced in optically active form, but both enantiomers sometimes arise in different genera and/or species or in a single species. Here we show through enantioselective total synthesis that the natural product isodehydrothyrsiferol shows partial enantiodivergency in that
最近,对映异构现象被发现为天然产物生物合成中的新现象。在自然界中,手性天然产物通常以旋光活性形式生产,但是两种对映异构体有时会以不同的属和/或物种或单个物种出现。在这里,我们通过对映选择性全合成显示,天然产物异十二氢甲状腺甾醇显示出部分对映异构性,因为九个或十个不对称中心中的六个与海洋角鲨烯衍生的三萜类甲状腺甾醇家族的其他成员的对映异构。此外,从同一生产商红藻Laurencia viridis中分离出了显示部分对映异构性的异去氢甲状腺甾醇和脱氢甲状腺甾醇。。这些结果表明,即使在源自单一物种的天然产物之间也可以形成部分对映体发散。
