Li, Bo’s team published research in Heterocycles in 2021 | CAS: 4637-24-5

N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5) belongs to anime.Typically the presence of an amine functional group is deduced by a combination of techniques, including mass spectrometry as well as NMR and IR spectroscopies. 1H NMR signals for amines disappear upon treatment of the sample with D2O. In their infrared spectrum primary amines exhibit two N-H bands, whereas secondary amines exhibit only one.Formula: C5H13NO2

Formula: C5H13NO2In 2021 ,《New and practical synthesis of GS-441524, the key intermediate of remdesivir》 appeared in Heterocycles. The author of the article were Li, Bo; Wang, Han; Sun, Cong; Lu, Sheng; Kang, LinLin; Jiang, Shun. The article conveys some information:

A new and practical synthesis of GS-441524, the key intermediate for remdesivir, is developed. 4-Amino-7-iodopyrrolo[2,1-f][1,2,4]triazine is protected by DMF-DMA, and reacted with 2,3,5-tri-O-benzyl-D-ribonolactone to give the product in 61% isolated yield. The next cyanation and debenzylation are carried out at -30° successively in 67% yield over two steps with >99% purity (HPLC). Purification methods of the intermediates and the final product involved in the route are developed. The results came from multiple reactions, including the reaction of N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5Formula: C5H13NO2)
