The Mn(Salen)-catalyzed oxidative kinetic resolution of secondary alcohols: reaction development and scope was written by Cheng, Qigan;Deng, Fanguo;Xia, Chungu;Sun, Wei. And the article was included in Tetrahedron: Asymmetry in 2008.HPLC of Formula: 65350-59-6 This article mentions the following:
A series of chiral Mn(Salen) complexes have been synthesized and submitted to the kinetic resolution of secondary alcs. bearing a large hindrance in the biphasic system, which is composed of water and CH2Cl2. After evaluating the appropriate complex, additive, and other conditions, chiral secondary alcs. were obtained with enantiomeric excesses of up to 98.6% in 6 min. In the experiment, the researchers used many compounds, for example, 1-Butyl-4-methylpyridin-1-ium bromide (cas: 65350-59-6HPLC of Formula: 65350-59-6).
1-Butyl-4-methylpyridin-1-ium bromide (cas: 65350-59-6) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.HPLC of Formula: 65350-59-6
