  Concise, Convergent Syntheses of (±)-Trichostatin A Utilizing a Pd-Catalyzed Ketone Enolate α-Alkenylation Reaction

  摘要：

  Two concise, convergent syntheses of (+/-)-trichostatin A (1), a potent histone deacetylase inhibitor, have been accomplished. The key step in both is a Pd-catalyzed alpha-alkenylation reaction between ketone 2 and either dienyl bromide 3 or alkenyl bromide 9 using a modification of cross-coupling conditions described by Negishi and Hartwig. A brief investigation has shown the potential utility of a Ni-catalyzed version of this reaction. The overall synthetic routes are short and amenable to scaleup, providing access to trichostatin A via trichostatic acid as a direct precursor.

  Embodiments herein relate to histone deacetylaces (HDACs) and HDAC inhibitors, such as trichostatin A (TSA) and TSA analogues. Embodiments provide simple methods of synthesizing TSA and TSA analogues. These methods provide routes of synthesis of TSA and TSA analogues that enable the production of the HDAC inhibitors at lower cost and in greater quantities than previously were available.

  本文涉及组蛋白去乙酰化酶（HDACs）和HDAC抑制剂，如三氯乙酸（TSA）及其类似物。实施例提供了合成TSA和TSA类似物的简单方法。这些方法提供了合成TSA和TSA类似物的途径，使得生产HDAC抑制剂的成本更低、数量更大，比以往更容易获得。
