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
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。
