Enantioselective vanadium-catalysed oxidation of aryl benzyl sulfides using Bolm’s procedure is accompanied by kinetic resolution in the oxidation of the resulting sulfoxides which enhances the enantiopurities of the sulfoxides recovered (typically >90 % ee), albeit with an associated reduction in yield. The effects of ligand, solvent and reaction conditions are discussed in detail.(© Wiley-VCH Verlag
使用 Bolm 程序对芳基苄基硫化物进行对映选择性钒催化氧化伴随着所得亚砜氧化的动力学拆分,这提高了回收的亚砜的对映纯度(通常 >90% ee),尽管伴随着产率的降低。详细讨论了配体、溶剂和反应条件的影响。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
