phosphate‐tether‐mediated ring‐closing metathesis reactions, which highlight the importance of product ring size and substrate stereochemical compatibility, as well as complexity, is reported. Studies focus primarily on the formation of bicyclo[n.3.1]phosphates, involving the coupling of C2‐symmetric dienediol subunits with a variety of simple, as well as complex, alcohol partners.
报告了一系列非对映选择性、磷酸盐系链介导的闭环复分解反应的例子,它们强调了产物环大小和底物立体化学相容性以及复杂性的重要性。研究主要集中在双环 [ n .3.1] 磷酸酯的形成上,涉及C 2对称二烯二醇亚基与各种简单和复杂的醇伙伴的偶联。

A synthesis of C11-desmethoxy soraphen A1α is described that proceeds in just 14 steps from readily available starting materials. This natural product analogue was identified as a target of interest in a program aimed at identifying novel natural product-inspired inhibitors of acetyl-CoA carboxylase (ACC) as potential anticancer therapeutics. While describing the most efficient synthesis of a soraphen
描述了 C11-去甲氧基 soraphen A 1α 的合成,该合成从容易获得的起始材料中仅通过 14 个步骤进行。这种天然产物类似物被确定为一项计划的目标靶点,该计划旨在将乙酰辅酶 A 羧化酶 (ACC) 的新型天然产物启发抑制剂作为潜在的抗癌疗法。在描述 soraphen A 1α类似物的最有效合成(据报道,天然产物的总合成以 25 到≥40 个线性步骤进行),我们还提供了支持 C11-杂原子功能是有益但不必要的结论的数据soraphen A 1α类似物抑制 ACC 的结构特征。
