  芳烃的选择性电化学氧化及单/多羰基化合物的制备

  摘要：

  在温和条件下开发了选择性电化学氧化。凭借这种电化学氧化，可以从不同的芳烃以中等至优异的产率和选择性制备各种单羰基和多羰基化合物。生成的羰基化合物可以在一锅反应中进一步转化为α-酮酰胺、高烯丙醇和肟。特别是，在单锅连续电解中制备了一系列 α-酮酰胺。机理研究表明，2,2,2-trifluoroethan-1-ol (TFE) 可以与催化剂物种相互作用并生成相应的氢键配合物，以提高电化学氧化性能。

  SeO2 mediated oxidative amidation of acetophenones, phenylacetylenes, and phenylacetaldehydes to α-ketoamides and aldehydes to amides is reported. Amidation selectively proceeds with secondary amines. α-Ketoamide derivatives of natural products 16-dehydropregnenolone acetate (8), pregnenolone acetate (10), and progesterone (11) were synthesized.

• Selenium dioxide-mediated synthesis of α-ketoamides from arylglyoxals and secondary amines

  日期：2012.8

  A facile and expeditious synthetic approach for the synthesis of alpha-ketoamides 3 is described. A series of alpha-ketoamides 3 was synthesized via reaction of selenium dioxide-mediated oxidative amidation between arylglyoxals 1 and secondary amines 2, and accelerated with microwave irradiation. Our findings indicate that constrained amines, such as piperazine and piperidine exhibit higher conversions for this transformation. This reaction was explored by synthesizing a series of alpha-ketoamides 3 from various arylglyoxals 1 with cyclic and acyclic secondary amines 2. (C) 2012 Elsevier Ltd. All rights reserved.

  Benzoylformamide (BFA) derivatives are proposed as new photocaged bases with good solubility in epoxy resin. Initially their structures were confirmed by H-1 NMR,C-13 NMR, and elemental analysis. Next, we detail their thermal stability, solubility behavior, and photolysis products. Furthermore, the model photo-latent anion polymerization (AP) of epoxide system in the presence of BFA-dBA (N,N-dibenzyl-2-oxo-2-phenylacetamide) as a photocaged base has been investigated, and excellent photopolymerization profile is obtained.
