The cyclopropenone catalyzed nucleophilic substitution of alcohols by methanesulfonate ion with inversion of configuration is described. This work provides an alternative to the Mitsunobu reaction that avoids the use of azodicarboxylates and generation of hydrazine and phosphine oxide byproducts. This transformation is shown to be compatible with a range of functionality. A cyclopropenone scavenge
描述了环丙烯酮通过甲磺酸根离子催化醇的亲核取代,且构型反转。这项工作为Mitsunobu反应提供了另一种选择,该方法避免了使用偶氮二羧酸盐以及生成肼和氧化膦副产物。已显示此转换与一系列功能兼容。已证明环丙酮清除策略有助于纯化。
