  A new and versatile synthetic route to Securinega alkaloids is reported. The first synthesis of allosecurinine has been accomplished in seven steps and 40% yield, starting from (+)-menisdaurilide, using a vinylogous Mannich reaction as the key transformation. Similarly, viroallosecurinine has been synthesized from (-)-menisdaurilide.

  isolated principally from subtropical plants belonging to the Phyllanthaceae family. Following a strategy based on alternative hypotheses for their biosynthesis, an easy and time-efficient divergent synthesis enabled access to twelve of those alkaloids featuring (neo)(nor)securinane skeletons. Moreover, this work permitted to reassign the absolute configurations of (+)-virosine B and (-)-episecurinol A

  A and B. We demonstrated that the relative stereochemistry at the C2 position of these advanced intermediates governs the fate of 1,2-amine shift leading to fluvirosaones A and B, respectively. While our synthetic design was inspired by the biosynthetic hypothesis of these natural products, syntheses of potential biosynthetic precursors and investigations of their chemical reactivity inversely have

  我们提出了一个简单的合成secu'amamine A，fluvirosaones A和B从容易获得的阿洛斯可宁和virallallosecurinine。这些天然产物的假定的生物合成前体，是（病毒）阿糖嘌呤的关键C2-烯胺衍生物，是通过VO（acac）2介导的区域选择性Polonovski反应首次获得的。该多能烯胺化合物的正式水合和1,2-胺转移提供了secu'amamineA。另一方面，该烯胺与TMS取代的甲基烯丙基碘化物试剂之间的正式氧化[3 + 2]环加成反应为推测的铺平了道路。 fluvirosaones A和B的生物合成前体。我们证明了这些高级中间体的C2位置处的相对立体化学分别控制导致fluvirosaones A和B的1，2-胺转移的命运。

  Starting from an enantiopure building-block serving as the chiral equivalent of 4-hydroxycyclohexa-2.5-dien-1-one, a diastereocontrolled synthesis of four cyclohexanoid butenolides has been investigated. The inherent convex-face selectivity exerted by the chiral building block was a key aspect of this method which afforded three of the five known butenolides, with only one losing its original chiral integrity during the conversion.
