    Construction of Fused Cyclooctanoid Ring Systems via Seven-Membered Ring Carbonyl Ylides
    摘要:
    一系列连接到环戊酮/环己酮/1-四氢萘酮单元的α-重氮羰基化合物通过使用重氮甲烷溶液,通过铑产生的羰基叶立德构建了各种融合的环辛烷环体系。铑(II)醋酸二聚体与各种α-重氮羰基化合物的反应生成了瞬态的七元环羰基叶立德,这些叶立德与亲二极体如N-苯基马来酰亚胺、对苯醌和DMAD进行了方便的1,3-偶极环加成反应,以串联方式提供了多种融合的环氧桥接环辛烷环体系。有趣的是,通过七元环羰基叶立德的分子内质子转移生成了一个oxepine环体系。当对苯醌作为亲二极体时,得到了一个三氧杂多环化合物。报道了对融合环辛烷类衍生物的单晶X射线分析,以明确确定融合环氧桥接环辛烷环体系的结构和立体化学;进一步分析揭示了固态结构中存在的独特分子间C-H···π相互作用模式。

    An improved method for the transformation of keto acids into cyclic α-hydroxy ketones, induced by the electrochemical generation of a novel acyl anion equivalent from the carboxy group, has been developed. Both five- and six-membered rings were constructed by constant-current electrolysis of δ- and ε-keto acids in the presence of Bu3P using an undivided cell equipped with a graphite anode and a Pt cathode. Attempts to prepare four- and seven-membered ring carbocycles were unsuccessful. The electrochemical reaction was found to be highly stereoselective when cyclization took place onto cyclopentanone and substituted cyclohexanone rings. Stereochemical aspects of the formation of bicyclic products, especially those having a bicyclo[4.3.0]skeleton, are discussed.
    开发了一种改进的方法,通过电化学生成从羧基衍生出的新型酰基阴离子等价物,诱导将酮酸转化为环状α-羟基酮。通过在配有石墨阳极和铂阴极的无隔膜电池中,在Bu3P存在下对δ-和ε-酮酸进行恒流电解,构建了五元和六元环。尝试制备四元和七元环碳环未能成功。当环化反应发生在环戊酮和取代环己酮环上时,发现该电化学反应具有高度立体选择性。讨论了双环产物形成的立体化学方面,特别是具有双环[4.3.0]骨架的产物。

    A series of α-diazo carbonyl compounds tethered to cyclopentanone/cyclohexanone/1-tetralone units have been synthesized using a diazomethane solution to construct various fused cyclooctane ring systems via rhodium-generated carbonyl ylides. The reaction of rhodium(II) acetate dimer with various α-diazo carbonyl compounds generated transient cyclic seven-membered ring carbonyl ylides, which underwent facile 1,3-dipolar cycloadditions with dipolarophiles, like N-phenylmaleimide, p-benzoquinone, and DMAD to furnish a variety of fused epoxy-bridged cyclooctane ring systems in a tandem manner. Interestingly, an oxepine ring system was generated via an intramolecular proton transfer of a seven-membered ring carbonyl ylide. A tri-oxa polycyclic compound was obtained in the case of p-benzoquinone as dipolarophile. A single-crystal X-ray analysis of a fused cyclootanoid derivative is reported to decisively establish the structure and stereochemistry of the fused epoxy-bridged cyclooctane ring systems; a further analysis revealed the existence of a unique intermolecular C–H···π interaction motif in the solid-state architecture.
