On March 31, 1988, Pozdnev, V. F. published an article.Application of 29704-38-9 The title of the article was Activation of carboxylic acids by pyrocarbonates. Synthesis of tert-butyl esters of N-substituted amino acids from di-tert-butyl pyrocarbonate in the presence of pyridine and 4-(dimethylamino)pyridine. And the article contained the following:
Several N-protected amino acids as well as 4-O2NC6H4CH2CO2H were converted into their tert-Bu esters by treatment with (Boc)2O (Boc = Me3CO2C) in the presence of pyridine and 4-(dimethylamino)pyridine. The Boc-protected amino acid tert-Bu esters were deblocked by treatment with p-MeC6H4SO3H in MeCN. The experimental process involved the reaction of tert-Butyl 2-(4-nitrophenyl)acetate(cas: 29704-38-9).Application of 29704-38-9
The Article related to tertbutyl ester protected amino acid, ditertbutyl pyrocarbonate esterification amino acid, pyridine tertbutyl esterification agent, Amino Acids, Peptides, and Proteins: Amino Acids and other aspects.Application of 29704-38-9
