dilution. These reactions were utilized to quantitatively examine the extent of retardation of medium-sized ring formation, compared to five- or six-membered ring formation. The order of reaction rates of formation of cyclic benzolactams is six- > five- > seven- > eight- > nine-membered ring at 25 °C. The present reaction provides a route to eight- and nine-membered benzolactams.
Herein, we report an efficient, tunable system for electrochemical reduction of ketones and phthalimides at room temperature without the need for stoichiometric external reductants. By utilizing NaN3 as the electrolyte and graphite felt as both the cathode and the anode, we were able to selectively reduce the carbonyl groups of the substrates to alcohols, pinacols, or methylene groups by judiciously
在此,我们报告了一种高效、可调的系统,用于在室温下电化学还原酮和邻苯二甲酰亚胺,无需化学计量的外部还原剂。通过使用 NaN 3作为电解质和石墨毡作为阴极和阳极,我们能够通过明智地选择溶剂和酸性添加剂,将基材的羰基选择性地还原为醇、频哪醇或亚甲基。反应条件与多种官能团兼容,邻苯二甲酰亚胺可以进行一锅还原环化反应,得到带有吲哚里西啶支架的产物。机理研究表明,反应涉及电子、质子和氢原子的转移。重要的是,N 3 /HN 3 循环作为氢原子穿梭运行,这对于将羰基还原为亚甲基至关重要。
