Safety of tert-Butyl carbamateIn 2020 ,《Direct enantioselective Mannich reactions of α-azido cyclic ketones: asymmetric construction of chiral azides possessing an α-quaternary stereocenter》 appeared in Chemical Communications (Cambridge, United Kingdom). The author of the article were Ye, Xueqian; Pan, Yongkai; Yang, Xiaoyu. The article conveys some information:
Direct enantioselective Mannich reactions of α-azido cyclic ketones with aldimines was realized through chiral phosphoric acid catalysis, which generate chiral azides possessing an α-quanternary stereocenter with complete regioselectivities and high diastereoselectivities and enantioselectivities. After reading the article, we found that the author used tert-Butyl carbamate(cas: 4248-19-5Safety of tert-Butyl carbamate)
tert-Butyl carbamate(cas: 4248-19-5) belongs to anime. Amines can be classified according to the nature and number of substituents on nitrogen. Aliphatic amines contain only H and alkyl substituents. Aromatic amines have the nitrogen atom connected to an aromatic ring.Important amines include amino acids, biogenic amines, trimethylamine, and aniline. Inorganic derivatives of ammonia are also called amines, such as monochloramine (NClH2).Safety of tert-Butyl carbamate
