  Stereoselection at the Steady State in Radical Cyclizations of Acyclic Systems Containing One Radical Acceptor and Two Precursors in a 1,5- Relationship under Pseudo-First-Order Conditions

  摘要：

  The first example of a successive kinetic resolution of acyclic diastereomeric radical intermediates in a 1,5-relationship under pseudo-first-order conditions is reported. A mechanistic model involves nonselective generation of the radical intermediates followed by different partitioning of these between two different chemical pathways. The "2,5-cis" selectivity in the radical cyclization step arises from transition geometries with the substituents aligned in pseudoequatorial positions.

  描述了一种用于制备替特罗辛1的合成策略，该蛋白是反刍动物中表现出抗生素，抗寄生虫和生长促进作用的酰基代太尼酸离子载体。关键步骤涉及金属介导的环化反应，该反应以高效的方式产生两个环和四个新的立体中心。这些立体中心中的三个的构型与合成四氢黄精蛋白所需的构型相同。其余的立体中心很容易在合成的后期异构化为天然构型。

  preparation of tetronasin 1, an acyltetronic acid ionophore demonstrating antibiotic, antiparasitic and growth promotion in ruminants is described. The key step involves a metal mediated cyclization reaction which creates two rings and four new stereocentres in a highly efficient manner. The configurations of three of these stereocentres are as required for the synthesis of tetronasin. The remaining stereocentre
