RuII-chiral amine complex has accomplished oxidative resolution of the 2-cyclopentene-1-ols having a bicyclo[2.2.1]heptene background to afford the cyclopentenones and the cyclopentenols both in good to excellent optical and chemical yields by an asymmetric hydrogen transfer reaction. The hydrogen transfer occurred selectively at the allylic methine hydrogen even though allylic methylene hydrogens are present
Ru II-手性胺配合物已经完成了具有双环[2.2.1]庚烯背景的2-环戊烯-1-醇的氧化拆分,从而通过不对称氢提供环戊烯酮和环戊烯醇,具有良好的光学和化学收率转移反应。即使烯丙基亚甲基氢存在于相同的相对位置,氢转移也选择性地发生在烯丙基次甲基氢上。
