  Direct Oxidation of N‐Benzylamides to Aldehydes or Ketones by N‐Bromosuccinimide

  摘要：

  A simple and efficient approach for the one-pot transformation of N-benzylamides to aldehydes or ketones under mild conditions was reported. All the 20 substrates gave moderate to excellent oxidative yields under the optimized conditions. Our study may provide a new approach for the one-pot synthesis of aldehydes or ketones from the corresponding amides.

  Fast and Regioselective Heck Couplings with N-Acyl-N-vinylamine Derivatives

  摘要：

  Highly regioselective Heck couplings of aryl triflates with N-acyl-N-vinylamines lacking an N-alkyl substituent were achieved with reaction times of approximately 1 h in yields ranging from 62 to 98% using 1.5 mol % of Pd-2(dba)(3), 3 mol % of DPPF, and diethylisopropylamine in dioxane. The efficiency of these cross-couplings were studied with several N-vinylamides and an example each of an N-vinylcarbamate and an N-vinylurea. The Heck coupling products easily underwent acidic hydrolysis to the corresponding aryl methyl ketone or in situ hydrogenation in the presence of (Ph3P)(3)RhCl under a hydrogen atmosphere to provide the N-acyl derivatives of pharmaceutically relevant benzylic amines. The coupling of a vinyl triflate and more interestingly a vinyl tosylate to N-vinyl acetamide was also studied affording a 2-acylamino-1,3-butadiene with the same high regioselectivity in preference for the alpha-isomer. This result suggests that Heck couplings of electron-rich alkenes with vinyl tosylates also follow a cationic pathway.

Reactions can be conducted without exclusion of oxygen and without the need of dry solvents. With tertiary α,α-dimethylbenzylic alcohols a different pathway involving a formal dimerization reaction takes place under the acid-catalytic conditions used. (© Wiley-VCH

With 0.1 mol% of complex 1, a broad range of ketones, including aryl ketones, dialkyl ketones, cyclic ketones, α-keto acids, α-keto esters and diketones, could be transformed to their corresponding primary amines with moderate to excellent yields (40%–95%). Asymmetric transformation was also attempted with chiral

  P411 heme enzymes enables intermolecular C−H amidation with high yields and exquisite enantioselectivity. The biocatalytic process utilizes stable hydroxamate esters as nitrenoid precursors and is amenable to scaleup. Mechanistic studies reveal rate-determining nitrenoid formation followed by a stepwise, hydrogen atom transfer-mediated C−H functionalization.
