An efficient method for the synthesis of N-acyl-benzotriazoles from a wide variety of protected amino acids, as well as from compounds frequently used in drug discovery such as biotin and N-Fmoc polyethyleneglycol, has been developed. The reaction of carboxylic acidderivatives with benzotriazole in the presence of T3P® yielded the corresponding N-acyl-benzotriazoles, which were obtained in high purity

Antiviral drug development for SARS-CoV-2: The design and microwave-assisted synthesis of pyrazine conjugates are reported. Some of the newly synthesized conjugates show better antiviral activity and selectivity indexes than those of the reference drug. All the lead compounds exhibited low cytotoxicity. Thus, these conjugates could lead to the development of potential drug candidates for SARS-CoV-2.

we report the synthesis, X-ray structure determination, and conformationalanalysis of a novel class of heteroatom-modified peptidomimetics, which we shall call “oxyazapeptides”. Substituting the typical native N-Cα bond with an O-Nα bond creates a completely new, previously unknown family of peptidomimetics, which are hydrolytically stable and display very interesting conformational behavior.

Herein we report a Ni-catalyzed reductive transamidation of conveniently available N-acyl benzotriazoles with alkyl, alkenyl, and aryl nitro compounds, which afforded various amides with good yields and a broad substrate scope. The same catalytic reaction conditions were also applicable for N-sulfonyl benzotriazoles, which could undergo smooth reductive coupling with nitroarenes and nitroalkanes to
在此,我们报道了一种方便获得的N-酰基苯并三唑与烷基、烯基和芳基硝基化合物的 Ni 催化还原转酰胺基反应,该反应以良好的收率和广泛的底物范围提供了各种酰胺。相同的催化反应条件也适用于N-磺酰基苯并三唑,它可以与硝基芳烃和硝基烷烃进行平滑的还原偶联,得到相应的磺酰胺。

A simple and practical approach for the synthesis of aromatic amides has been developed using N‐Acyl‐Benzotriazole derivatives and aromaticamines including anilines (ABAA reaction). The reaction is performed in acidic medium, is selective for the coupling of aromaticamines vs. aliphatic amines, and features broad functional group tolerance.
