  Arylboronic Acid Catalyzed C-Alkylation and Allylation Reactions Using Benzylic Alcohols

  摘要：

  The arylboronic acid catalyzed dehydrative C-alkylation of 1,3-diketones and 1,3-ketoesters using secondary benzylic alcohols as the electrophile is reported, forming new C-C bonds (19 examples, up to 98% yield) with the release of water as the only byproduct. The process is also applicable to the allylation of benzylic alcohols using allyltrimethylsilane as the nucleophile (12 examples, up to 96% yield).

  weak C−O bond. Spontaneous scission results in the formation of the stable nitroxyl radical TEMPO. as well as a reactive carbocation intermediate that can be intercepted by a wide range of nucleophiles. Notably, this process occurs under neutral conditions and at comparatively mild potentials, enabling catalytic cation generation in the presence of both acid sensitive and easily oxidized nucleophilic

  描述了一种新的催化方法，该方法通过烷氧基胺自由基阳离子的介观裂解来获得碳正离子中间体。在此过程中，激发态氧化剂与TEMPO衍生的烷氧基胺底物之间的电子转移会产生带有非常弱的C-O键的自由基阳离子。自发断裂导致形成稳定的硝基自由基TEMPO 。以及可被多种亲核试剂截获的反应性碳正离子中间体。值得注意的是，该过程在中性条件下和相对温和的电势下发生，从而在酸敏感和易氧化的亲核分子同时存在的情况下能够产生催化阳离子。

  and direct transformation of carboxamides are two exciting areas that have attracted considerable attention in recent years. We report herein that secondary amides, the least reactive derivatives of carbonyl compounds, upon activated with triflic anhydride, can serve as effective hydroacylating reagents in partner with alkenes to yield ketones at ambient temperature. The method was applied to the one‐step

  烯烃的直接官能化和羧酰胺的直接转化是近年来令人瞩目的两个令人兴奋的领域。我们在此报道，仲酰胺，即羰基化合物的反应性最低的衍生物，在用三氟甲磺酸酐活化后，可以与烯烃一起作为有效的氢酰化试剂，在环境温度下产生酮。该方法已用于外消旋二氢芳基羟色酮的一步合成。在这种方法中，烯烃用作有机金属试剂的替代物，从而可以进行正交的化学选择性反应。许多烯烃（如camp烯和降冰片烯）的现成性允许一步合成酮，而传统方法则需要几个步骤。

  Chiral phosphoric-acid-catalyzed asymmetric reductions of trans-chalcones have been investigated in this work. A BINOL-derived boro-phosphate-catalyzed asymmetric transfer hydrogenation of the carbon–carbon double bond of trans-chalcone derivatives employing borane as a hydride source was realized. This methodology provides a convenient procedure to access chiral dihydrochalone derivatives in high

  aryltrialkoxysilanes to alpha,beta-unsaturated carbonyl compounds (ketones, aldehydes) and nitroalkenes in the presence of SbCl(3), TBAF, AcOH, and a catalytic amount of Pd(OAc)(2), in CH(3)CN at 60 degrees C, provides the corresponding conjugate addition products in moderate to good yields. The addition of equimolar amounts of SbCl(3) and TBAF is necessary for this reaction to proceed smoothly. The arylpalladium

  The solid acid, tin hydroxide-embedded montmorillonite, catalyzes the unprecedented alkylation of various silicon enolates with primary, secondary and tertiary benzylic alcohols as well as secondary allylic alcohols. The acid catalysis of Sn-Mont was not only higher than that of the other ion-exchanged montmorillonites (M-Mont; M = H, Ti, Fe and Al), but also higher than that of the typical homogeneous
