In 2010,Yu, Shouyun; Ishida, Hiroshi; Juarez-Garcia, M. Elisa; Bode, Jeffrey W. published 《Unified synthesis of enantiopure β2h, β3h and β2,3-amino acids》.Chemical Science published the findings.Name: tert-Butyl N,N’-diisopropylcarbamimidate The information in the text is summarized as follows:
A single chiral auxiliary and synthetic route can be used for a three-step (cycloaddition, auxiliary removal and fragmentation) preparation of enantiopure β3h, β2h and β2,3-amino acids (>99% ee). This approach works for a wide variety of both natural and unnatural side chains, provides access to either enantiomeric form, and can be executed on a preparative scale without recourse to column chromatog. After reading the article, we found that the author used tert-Butyl N,N’-diisopropylcarbamimidate(cas: 71432-55-8Name: tert-Butyl N,N’-diisopropylcarbamimidate)
tert-Butyl N,N’-diisopropylcarbamimidate(cas: 71432-55-8) belongs to anime. Examples of direct uses of amines and their salts are as corrosion inhibitors in boilers and in lubricating oils (morpholine), as antioxidants for rubber and roofing asphalt (diarylamines), as stabilizers for cellulose nitrate explosives (diphenylamine), as protectants against damage from gamma radiation (diarylamines), as developers in photography (aromatic diamines), as flotation agents in mining, as anticling and waterproofing agents for textiles, as fabric softeners, in paper coating, and for solubilizing herbicides.Name: tert-Butyl N,N’-diisopropylcarbamimidate
