trans-alkenes followed by a mild and highly regioselective isomerization to give the major ketone isomers in 66-98% yield. Preliminary kinetics and isotope labeling studies suggest epoxide ring opening as the turnover limiting step in our proposed mechanism. A similar catalytic system was applied to the kinetic resolution of select trans-epoxides to give synthetically useful selectivity factors of 17-23
我们报告了内烯烃的瓦克氧化的替代途径,包括反式烯烃的环氧化,然后是温和且高度区域选择性的异构化,以 66-98% 的产率得到主要的酮异构体。初步动力学和同位素标记研究表明
环氧化物开环是我们提出的机制中的周转限制步骤。将类似的催化系统应用于选择的反式
环氧化物的动力学拆分,为苄基取代的底物提供 17-23 的合成有用选择性因子。
