  Palladium-Catalyzed Isomerization of Aryl-Substituted Epoxides:  A Selective Synthesis of Substituted Benzylic Aldehydes and Ketones

  摘要：

  Aryl-substituted epoxides bearing multiple methyl substituents on the epoxide ring isomerize in the presence of 5 mol % Pd(OAc)(2)PR3 (R = n-Bu, Ph) to form the corresponding benzylic aldehyde or ketone, with complete regioselectivity for the carbonyl compound formed via cleavage of the benzylic C-O bond. No allylic alcohols or products arising from alkyl migration are observed. Rapid reaction rates and nearly quantitative yields are obtained, even with highly sterically hindered epoxides, using tri-n-butylphosphine as ligand and tert-butyl alcohol as solvent. 2-Aryl-substituted epoxides with two methyl substituents on C3 are completely unreactive, consistent with an oxidative addition/beta-hydride elimination mechanism. Catalyst variation studies show that both Pd(OAc)(2) and PR3 are essential for optimal activity and that palladium catalysts formed in this manner are superior to other Pd(O) catalysts (e.g., Pd(PPh3)(4)). The reactivity of catalytic Pd(OAc)(2)/PR3 toward multiply-substituted epoxides is compared to traditional Lewis acid catalysts; the former is found to be much more selective for isomerization without skeletal rearrangement. A mechanistic rationale involving turnover-limiting S(N)2-like attack of Pd(O) at the benzylic carbon is proposed.

  The total syntheses of four polyketides, surinone B (1), alatanones A–B (2–3), and trineurone A (4) were accomplished through an efficient and unified strategy via one-pot C-acylation reaction coupling 1,3-cyclohexadiones with EDC-activated acids under mild conditions. Alatanone A (2) was found to be a potent anti-microbial agent against Gram-positive and Gram-negative bacteria with MIC 31.25 μg/ml

  Simple, mild, and efficient conditions are reported for a Pd(0)-catalyzed Heck reaction that delivers high yields and selectivity for (E)-styrenyl products using electronically nonbiased olefin substrates bearing a range of useful functionality. Preliminary mechanistic studies demonstrate that the σ-donating DMA solvent is crucial for high selectivity. Further studies suggest that the catalyst distinguishes

• Synthesis of antifungal alatanone and trineurone polyketides
  作者：Alexander R. Lewis、Keith P. Reber

  DOI：10.1016/j.tetlet.2016.01.090

  日期：2016.3

  The antifungal polyketides alatanones A and B and trineurones A–E have been synthesized using a one-pot C-acylation reaction coupling 1,3-cyclohexanediones with the appropriate carboxylic acids. This key transformation is believed to proceed via initial carbodiimide-mediated O-acylation followed by a DMAP-catalyzed Claisen–Haase rearrangement, resulting in O to C acyl migration.

  抗霉菌的聚酮化合物A和B以及三氮酮A-E是通过一锅C-酰化反应合成的，将1，3-环己二酮与适当的羧酸偶联。据信，这种关键的转化是通过最初的碳二亚胺介导的O-酰化，然后是DMAP催化的Claisen-Haase重排进行的，从而导致O到C的酰基迁移。
