Authors introduce an organocatalytic approach for oxaziridinium-mediated C-H hydroxylation that employs secondary amines as catalysts. Authors also demonstrate the advantages of this operationally simple catalytic strategy for achieving high yielding and highly selective remote hydroxylation of compounds bearing oxidation-sensitive functional groups such as alcs., ethers, carbamates, and amides. By employing hexafluoroisopropanol as the solvent in the absence of water, a proposed hydrogen-bonding effect leads to, among other advantages, as high as ≥99:1 chemoselectivity for remote aliphatic hydroxylation of 2° alcs., an otherwise unsolved synthetic challenge normally complicated by substantial amounts of alc. oxidation Initial studies of the reaction mechanism indicate the formation of an oxaziridinium salt as the active oxidant and a C-H oxidation step that proceeds in a stereospecific manner via concerted insertion or hydrogen atom-transfer/radical rebound. Furthermore, preliminary results indicate that site selectivity can be affected by amine catalyst structure. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Reference of 106-21-8).
3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Reference of 106-21-8
