  • A Ruthenium-Catalyzed, Novel and Facile Procedure for the Conversion of Vicinal Dihaloalkenes to α-Diketones

    transition metal chemistry, used in the preparation of variety of heterocycles and natural products. α-Diketones also function as the key elements in the Weiss reaction and in the construction of rigid molecular assemblies (molecular wires, rods, etc.) based on ‘block’ chemistry. Some of the common methods to obtain α-diketones are: (i) oxidation of αhydroxyketones, (ii) oxidation of alkynes, and (iii)
    丰富的官能团以及在各种键形成反应中创建、相互转化和利用它们的大量方法是设计任何目标分子化学合成的重要资产。α-二酮是两个相邻羰基的强大组合,由于其广泛的应用而备受关注。α-二酮表现出有趣的光化学,用作调味剂,用作过渡金属化学中配体的前体,用于制备各种杂环和天然产物。α-二酮也是 Weiss 反应和基于“嵌段”化学的刚性分子组件(分子线、棒等)的构建中的关键元素。获得 α-二酮的一些常用方法是: (i) α-羟基酮的氧化,(ii) 炔烃的氧化,和 (iii) α-亚甲基酮的氧化。尽管烯烃的受控氧化很困难,但据报道,KMnO4/Ac2O 会产生低到中等产率的 α-二酮和副产物。但是,该方法不适用于小环(环辛烯以下)和双环系统。我们发现,邻位二卤代烯烃可以作为掩蔽的 α-二酮(方案 1)。我们特别选择了

    The tricyclic alpha-keto hemiacetals 3a,b and 8a-d obtained from ruthenium-catalyzed oxidation of tetrahalonorbornyl derivatives possessing a pendant hydroxymethyl group were cleaved using Pb-(OAc)(4) or alkaline H2O2 to give gamma-lactone-fused cyclopentane derivatives 5a,b and 9a-d. The a-keto hemiacetal 3b has also been elaborated to spiroepoxide derivative 25. The stable hydrate 4 formed from ruthenium-catalyzed oxidation of acrolein adduct 10 furnished an intramolecular hemiacetal 11 upon cleavage with Pb(OAc)(4). The alpha-halo ester moiety in 5a was transformed smoothly in a highly regio- and stereoselective manner to alpha-hydroxy esters through a lactone-assisted intermediate to furnish 18.

    The addition of allyl magnesium and allyl indium reagents to a key TBS protected norbornenyl building block, synthesised in 6-steps from commercially available 1,1-dimethoxy-2,3,4,5-tetrachlorocyclopentadiene, has been achieved providing the syn addition products with high diastereoselectivity. The subsequent exposure of the addition products to metathesis conditions, in the presence of ethene, then provided cis fused[3.0.3]-carbocycles with very high regioselectivity, via a Ring Rearrangement Metathesis (RRM) transformation.
