  Carboxyl activation via silylthioesterification: one-pot, two-step amidation of carboxylic acids catalyzed by non-metal ammonium salts

  摘要：

  The first organo-catalyzed silylthioesterification of a carboxylic acid and a commercially available mercaptoorganosilane results in the in situ production of an O-silylthionoester. Subsequent amine addition forms amides in an operationally simple one-pot procedure without removal of water. The scope and efficiency of these reactions with respect to the catalyst, carboxylic acid, amine, [Si-S] moiety, and solvent are investigated. A number of functionalities are tolerated in the two-step amidation including alkene, alkyne, alkyl and aryl halides, benzylic ethers, and heterocycles with free coordinating sites.

  range of amines. In most cases, the amide products can be purified by a simple filtration procedure using commercially available resins, with no need for aqueous workup or chromatography. The amidation of N-protected amino acids with both primary and secondary amines proceeds effectively, with very low levels of racemization. B(OCH2CF3)3 can also be used for the formylation of a range of amines in good

  B(OCH 2 CF 3 ) 3由易得的B 2 O 3和2,2,2-三氟乙醇制备，是一种有效的试剂，可用于多种羧酸与多种胺的直接酰胺化。在大多数情况下，可以使用市售树脂通过简单的过滤程序纯化酰胺产物，无需进行水处理或色谱法。N-保护的氨基酸与伯胺和仲胺的酰胺化有效进行，外消旋化水平非常低。B(OCH 2 CF 3 ) 3 通过二甲基甲酰胺的转酰胺基作用，也可用于一系列胺的甲酰化反应，收率良好至极好。

  Amidst the green: A green, mild and effective protocol for the direct formation of secondary and tertiary amides from non‐activated carboxylic acids and amines in good to excellent yields by employing ZrCl4 as the catalyst is presented (see scheme). The amide coupling protocol proved to be suitable for scaled up syntheses, and the mild reaction conditions conserve the enantiopurity of chiral starting
