  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.

  hydroalkylamination and hydroamidation of styrenes have been developed by NiH catalysis with a simple bioxazoline ligand under mild conditions. A wide range of enantioenriched benzylic arylamines, alkylamines and amides can be easily accessed by nitroarenes, hydroxylamines and dioxazolones, respectively as amination reagents. The chiral induction in these reactions is proposed to proceed through an enantiodifferentiating

  In the presence of Co2(CO)8 and additives, propargyl alcohol derivatives could be reduced to alkenes in moderate to good yield. The selectivity of this reaction could be controlled by adding different additives: with H2O as the additive, the major configuration of product is Z‐alkene; with CF3COOH as the additive, the major configuration of product is E‐alkene.

  日期：2017.10

  α-azidoketones starting from olefins have been developed by employing catalytic oxidation of the intermediary bromohydrins with in situ-generated modified IBX as the key reaction. The improved procedure involves initial formation of bromohydrin by the reaction of olefin with NBS in acetonitrile-water mixture (1:1) at rt followed by oxidation with in situ-generated 3,4,5,6-tetramethyl-2-iodoxybenzoic acid (TetMe-IBX)

  通过将中间溴代醇催化氧化与原位生成的修饰IBX作为关键反应，已经开发出了简单的一锅法，用于从烯烃开始合成α-溴代酮和α-叠氮酮。改进的方法包括通过在室温下使烯烃与NBS在乙腈-水混合物（1：1）中反应，然后再用原位生成的3,4,5,6-四甲基-2-碘氧基苯甲酸（（TetMe-IBX），以催化量由3,4,5,6-四甲基-2-碘苯甲酸和Oxone制得。使用NaN 3 / NaHCO 3在同一个锅中将α-溴酮进一步转化为相应的α-叠氮酮。一锅转换对于包括环以及无环脂族烯烃以及富电子和缺电子的苯乙烯在内的多种烯烃是通用的。对于同时含有富电子和不足双键的底物，已证明了富电子双键的化学选择性溴羟基化和随后的氧化成α-溴代酮。
