  A Concise, Selective Synthesis of the Polyketide Spacer Domain of a Potent Bryostatin Analogue

  摘要：

  [GRAPHICS]A concise, asymmetric synthesis of the polyketide spacer domain portion (C1-C13) of a highly potent bryostatin analogue was developed. The route utilizes asymmetric hydrogenation methodology to install the C3, C5, and C11 stereocenters, while a substrate directed syn reduction sets the C9 stereocenter. The spacer domain 1 is obtained in 10 steps with a 25% overall yield and is readily incorporated into the synthesis of 2.

• Total Synthesis and Initial Biological Evaluation of New B-Ring-Modified Bryostatin Analogs
  作者：Paul A. Wender、Joshua C. Horan、Vishal A. Verma

  日期：2006.11.9

  [Structure: see text] The total synthesis and preliminary biological evaluation of the first bryostatin analogs (bryologs) to incorporate B-ring substitution are reported. Asymmetric syntheses of two new polyketide "spacer" domains are described, one exploiting the pseudosymmetry of the C1-C13 region. These fragments are convergently joined to the "recognition" domain through a remarkably versatile

  [结构：见正文]报告了第一个纳入B环取代的bryostatin类似物（bryologs）的总合成和初步生物学评估。描述了两个新的聚酮化合物“间隔”域的不对称合成，其中一个利用了C1-C13区域的拟对称性。这些片段通过非常通用的宏缩醛化过程会聚到“识别”域。所得的新类似物对蛋白激酶C（PKC）表现出强大的纳摩尔或皮摩尔亲和力，与溴代他汀相似或更好。
• Efficient Synthetic Access to a New Family of Highly Potent Bryostatin Analogues via a Prins-Driven Macrocyclization Strategy
  作者：Paul A. Wender、Brian A. DeChristopher、Adam J. Schrier

  DOI：10.1021/ja8015632

  日期：2008.5.1

  The step-economical synthesis of a new class of bryostatin analogues that contain the complete oxycarbocyclic core ring system of the bryostatin natural products is reported. These agents are convergently assembled via a highly efficient, functional-group-tolerant, and stereoselective Prins-driven macrocyclization. These tetrahydropyranyl B-ring analogues are among our most potent and efficacious analogues to date, exhibiting nanomolar and picomolar activities in protein kinase C affinity assays as well as in cellular antiproliferation assays.
