On April 30, 2000, Hoffmann, Reinhard W.; Caturla, Francisco; Lazaro, Miguel A.; Framery, Eric; Carmen Bernabeu, M.; Valancogne, Ingrid; Montalbetti, Christian A. G. N. published an article.Formula: C23H19BrN2O4 The title of the article was Conformational analysis of 4-amido-2,4-dimethylbutyric acid derivatives. And the article contained the following:
Several protected 4-amido-2,4-dimethylbutyrates were prepared Both, syn- and anti-4-amido-2,4-dimethylbutyric acid derivatives were found to populate a conformation in which the amido group is gauche to the main chain of the mol. In the anti series, a single conformation predominates, in which the acid carbonyl group is also gauche to the main chain. In the syn series, two local conformers prevail about the C(2)-C(3) bond. The experimental process involved the reaction of (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(5-bromopyridin-2-yl)propanoic acid(cas: 282734-37-6).Formula: C23H19BrN2O4
The Article related to amidomethylbutyrate preparation conformation, butyrate amido methyl preparation conformation, Amino Acids, Peptides, and Proteins: Amino Acids and other aspects.Formula: C23H19BrN2O4
