  A palladium-catalyzed N-acylation of tertiary amines by carboxylic acids was achieved through C–N cleavage. This reaction showed a wide substrate scope. Both aromatic and aliphatic acids served well as the acylating reagents and coupled with tertiary amines to produce the corresponding amides in good to excellent yields. With the strategy, bioactive carboxylic acids were also efficiently modified,

  通过C–N裂解，实现了羧酸对钯催化的叔胺的N-酰化反应。该反应显示出较宽的底物范围。芳族和脂族酸都很好地用作酰化剂，并与叔胺偶联以良好或优异的产率产生相应的酰胺。通过该策略，还可以有效地修饰生物活性羧酸，从而突出了该方法在有机合成中的合成价值。

  Methods are described for efficient and regioselective reactions that are Ru-catalyzed and either (i) amide-directed C—H, C—N, C—O activation/C—C bond forming reactions, (ii) ester-directed C—O and C—N activation/C—C bond forming reactions, or (iii) amide-directed C—O activation/hydrodemethoxylation reactions. All of these reactions of directed C—H, C—N, C—O activation/coupling reactions establish a catalytic base-free DoM-cross coupling process at non-cryogenic temperature. High regioselectivity, yields, operational simplicity, low cost, and convenient scale-up make these reactions suitable for industrial applications. Many previously unknown amide-substituted or ester-substituted aryl and heteroaryl compounds are presented with synthetic details also provided.

  描述了一种高效和区域选择性反应的方法，这些反应是以钌为催化剂的，可以是（i）酰胺导向的C—H、C—N、C—O活化/C—C键形成反应，（ii）酯导向的C—O和C—N活化/C—C键形成反应，或者（iii）酰胺导向的C—O活化/脱甲氧基反应。所有这些导向C—H、C—N、C—O活化/偶联反应在非低温下建立了一个无催化剂碱的DoM-交叉偶联过程。高区域选择性、产率、操作简便、低成本和便于放大规模使得这些反应适用于工业应用。还提供了许多以前未知的酰胺取代或酯取代的芳基和杂环芳基化合物，同时提供了合成细节。

  acid chlorides to give amides is disclosed. Reactions are carried out in the presence of silver acetate in non-aqueous environments under heterogeneous phase conditions. Amides are easily recovered in very good to excellent yields and without racemization. The approach is successful in forming peptide bonds starting from N-(4-nitrobenzenesulfonyl)-amino acid chlorides and allows the formation of dipeptides

  A one-pot synthesis of secondary and tertiary amides from carboxylic acids and amines by using SOCl2 has been developed. Also when sterically hindered amines were used as the starting materials, excellent yields of the corresponding amides were obtained. The amidation of N-protected α-amino acids with secondary amines proceeds effectively with good yields. The process works well also in the presence
