77Se and 13C NMR Characterization of Selenium Cyanides

Autor: João Marcos Anghinoni, Sabrina Souza Ferreira, Filipe Penteado, Eder João Lenardão, Márcio Santos Silva

Publikováno v: Molbank, Vol 2022, Iss 4, p M1485 (2022)

Here, we describe a magnetic resonance spectroscopy characterization of selenium cyanide compounds, Se(CN)2, Se2(CN)2 and Se3(CN)2. Selenim-77 and carbon-13 nuclides were used to provide data of these species at room temperature. This is the first st

Publikováno v: Molbank, Vol 2022, Iss 1, p M1330 (2022)

Here we describe the functionalization of lupulone natural compound in obtaining 3-isobutyl-5,5,7-tris(3-methylbut-2-en-1-yl)-1-phenyl-1,7-dihydro-4H-indazole-4,6(5H)-dione. The lupulone-H-indazole derivative was prepared with 75% yield through the r

NMR chiral recognition of lipoic acid by cinchonidine CSA: A stereocenter beyond the organic function

Autor: Talia Behnen Marta, Augusto Cardozo Argondizzo, Robson da Silva Oliboni, Márcio Santos Silva

Publikováno v: Chirality. 35:40-48

Alpha-lipoic acid is a natural product that possesses distinct pharmacological properties. Lipoic acid is a short-chain fatty acid containing an asymmetric carbon at five bonds of distance to the organic function. Herein, we developed a nuclear magne

77Se Nuclear Magnetic Resonance: Experiments and In Silico Approaches

Autor: Márcio Santos Silva, Laura Orian

Publikováno v: Chalcogen Chemistry: Fundamentals and Applications ISBN: 9781839164224

77Se NMR signals are very sensitive to the chemical environment of the selenium atom. This explains the successful application of this spectroscopic technique in the numerous fields in which this chalcogen is involved, including organic catalysis and
