Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 1072-62-4, Name is 2-Ethyl-1H-imidazole, molecular formula is C5H8N2, belongs to imidazoles-derivatives compound, is a common compound. In a patnet, author is Mata, Lara, once mentioned the new application about 1072-62-4, Quality Control of 2-Ethyl-1H-imidazole.
Stereocontrolled Ring-Opening of a Hindered Sulfamidate with Nitrogen-Containing Aromatic Heterocycles: Synthesis of Chiral Quaternary Imidazole Derivatives
This paper explores the role of a hindered cyclic sulfamidate derived from alpha-methylisoserine as an electrophile in a nucleophilic displacement reaction with nitrogen-containing aromatic heterocycles. Several imidazoles and pyrazole were tested as nucleophiles in the absence of an additional base to give the corresponding ring-opening compounds: We show that the process takes place by inversion of the configuration of the quaternary electrophilic center, retaining the enantiomeric excess of the starting sulfamidate. This reaction opens the way to obtain important quaternary imidazole derivatives such as an innovative type of bis-amino add related to histidinoalanine and a novel alpha,alpha-disubstituted beta-amino acid(beta(2,2)-amino acid)
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 1072-62-4. The above is the message from the blog manager. Quality Control of 2-Ethyl-1H-imidazole.
