Zhang, Cong-Cong; Chen, Li-Jun; Shen, Bao-Chun; Xie, Hui-Ding; Li, Wei; Sun, Zhong-Wen published their research in Organic & Biomolecular Chemistry in 2021. The article was titled 《Enantioselective decarboxylative Mannich reaction of β-keto acids with C-alkynyl N-Boc N,O-acetals: access to chiral β-keto propargylamines》.Related Products of 4248-19-5 The article contains the following contents:
A concise and efficient method for the enantioselective synthesis of β-keto propargylamines via chiral phosphoric acid-catalyzed asym. Mannich reaction between β-keto acids and C-alkynyl N-Boc N,O-acetals as easily available C-alkynyl imine precursors was demonstrated, affording a broad scope of β-keto N-Boc-propargylamines in high yields (up to 97%) with generally high enantioselectivities (up to 97 : 3 er). After reading the article, we found that the author used tert-Butyl carbamate(cas: 4248-19-5Related Products of 4248-19-5)
tert-Butyl carbamate(cas: 4248-19-5) 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.Related Products of 4248-19-5
