Herein we present a full account on the reductive Hosomi-Sakurai reaction along with some insight into the reaction mechanism. Stereoselectivity appears to be highest when the crucial carbocation intermediate, derived by protonation of the homoallylic ether, is sufficiently stabilized to ensure that the hydride transfer becomes rate-determining. This hypothesis is supported by experiment and mechanistic
在本文中,我们对还原性细小樱井反应进行了全面介绍,并对反应机理进行了深入了解。当通过均烯丙基醚的质子化作用衍生的关键碳正离子中间体足够稳定以确保氢化物转移成为速率决定性化合物时,立体选择性似乎最高。该假设得到实验和机理分析的支持。
