    Alternative Spiroketalization Methods toward Purpuromycin: A Hemiketal Conjugate Addition Strategy and Use of an Electron-Rich Isocoumarin Precursor
    摘要:
    Two methods are presented that were designed to circumvent the persistent problem of benzofuran formation and instead yield a spiroketal of the rubromycin family type. First, using an alternative disconnection, a hemiketal conjugate addition to a naphthaquinone electrophile was investigated. Synthesis of the requisite electrophile provided insight into the selective oxidation and functionalization of the naphthalene portion. Second, the electronic features of the isocoumarin ring system were adjusted, and the corresponding reactivity further supports the hypothesis that electron-rich isocoumarins are capable of spiroketalization. Robust, flexible syntheses from simple precursors were developed that allowed multiple reduced isocoumarins to be generated. Combined, the data presented herein give insight into the sensitivities of this family and illuminate other potential methods of spiroketalization. In addition, the convergent assembly of substrates containing different naphthaquinone and isocoumarin subunits highlights the utility of our 1,3-dipolar cycloaddition approach to generate analogs of these structures for SAR, as well as chemical reactivity studies.

  • Preparation of Highly Alkoxy-Substituted Naphthaldehyde Derivatives – A Regioselective Approach to Building Blocks for the Synthesis of Rubromycins

    substituted and regioselectively protected naphthaldehyde derivative 8b. The synthesis of this key compound could be achieved in a 12-step sequence in an overall yield of 9 %. Our planned rubromycin synthesis was successfully verified by the conversion of 8b into the protected α-hydroxy enone 7b by addition of lithiated methoxyallene followed by hydrolysis and subsequent silylation of intermediate 7a.

    红霉素家族化合物的计划合成需要高度取代的醛衍生物 8 的有效合成。尝试了三种不同的途径来实现这一目标。路线 I 从 1,5-二羟基萘 (10) 开始,并以简单的顺序以中等总产率获得五烷氧基取代的醛 17。路线II采用芳炔环加成来生成官能化骨架。这个序列顺利地提供了生物 19,它作为醛 24、硼酸 25 的非常合适的前体,最后是不对称取代的六烷氧基生物 18。 然而不幸的是,18 的区域选择性甲酰化以提供所需的醛 8a可能的,这种关键化合物只能以低收率获得。尽管 O-烯丙基化衍生物 30 的 Claisen 重排尝试提供了错误的区域异构体 33,但容易获得的氨基甲酸酯 34 的邻位 Fries 重排顺利提供了预期的酰胺 35,结果证明它基本上是惰性的,无法转化为相应的甲醚 8b。因此,我们开发了路线 III,包括替代的芳烃环加成和随后的三环加合物 41 的区域选择性开环。该序列使我们能够有效地制备缩醛

    A concise synthesis of naphthalene compounds for incorporation into a synthetic sequence for the rubromycin family of natural products is presented. These highly substituted naphthalenes are generated in seven and nine steps, respectively, from 2,4,5-trimethoxybenzaldehyde. Three ring-forming methods were explored and the controlled oxygenation of different positions was investigated to yield differentially
