  The catalytic role of PPh3 and its polymer bound analog was investigated in the 2,4,6-trichloro-1,3,5-triazine (TCT) mediated amidation of carboxylic acids. In the presence of inorganic bases which were inert toward TCT, carboxylic acids rapidly reacted with amines to afford amides in good to excellent yields. The described method also enabled the synthesis of optically active protected dipeptides

• Amidines. VII. Hydrolysis and alcoholysis of carboxamides under mild conditions.

  Hydrolysis and alcoholysis of carboxamides derived from primary aliphatic amines were achieved under mild conditions. Amide exchange reaction between carboxamides and N1-acyl-N1, N2-di (p-nitrophenyl) formamidines (1) gave N1-acyl-N1-alkyl-N2-(p-nitrophenyl)formamidines (2) which were readily hydrolyzed or alcoholyzed to give N1-alkyl-N2-(p-nitrophenyl)formamidines (4) and carboxylic acid or its ester. Compounds 4 were hydrolyzed to give aliphatic amine and N-formyl-p-nitroaniline in the presence of acetic acid or hydrochloric acid at room temperature. For the alcoholysis of N-acyl derivatives of amino alcohols, protection of the hydroxyl substituent by an acyl group was essential because the reaction of 1 and N-acyl derivatives of amino alcohols was quite complex. Alcoholysis of N-ethyl-N, N'-ethylenebis (p-chlorobenzamide) (8a) by this method gave N-(2-aminoethyl)-N-ethyl-p-chlorobenzamide (8b). Thus, the selective alcoholysis of diacyl derivative of diamines, which contain primary and secondary amino groups, was achieved.

  在温和条件下，实现了由伯脂肪胺衍生的羧酰胺的水解和醇解。羧酰胺与N1-酰基-N1,N2-二（对硝基苯基）甲酰亚胺（1）之间的酰胺交换反应产生了N1-酰基-N1-烷基-N2-（对硝基苯基）甲酰亚胺（2），这些化合物容易发生水解或醇解，生成N1-烷基-N2-（对硝基苯基）甲酰亚胺（4）和羧酸或其酯。化合物4在乙酸或盐酸存在下室温水解，产生脂肪胺和N-甲酰基-对硝基苯胺。对于氨基醇的N-酰基衍生物的醇解，通过酰基保护羟基取代基是必要的，因为1与氨基醇的N-酰基衍生物的反应非常复杂。通过这种方法，N-乙基-N,N'-乙烯基双（对氯苯甲酰胺）（8a）的醇解生成了N-（2-氨基乙基）-N-乙基-对氯苯甲酰胺（8b）。这样，实现了含有伯和仲氨基的二胺二酰基衍生物的选择性醇解。

  of N–H bonds with alkanes using a photoinduced copper(II) peroxide catalytic system. Upon light irradiation, the peroxide serves as a hydrogen atom transfer reagent to activate stable C(sp3)–H bonds for the reaction with a broad range of nitrogen nucleophiles. The method enables the chemoselective alkylation of amides and is utilized for the late-stage functionalization of N–H bond containing pharmaceuticals
