Computational analysis of the triflimide catalyzed [3,3]-sigmatropic rearrangement of N-allylhydrazones, using density functional theory calculations, is reported. Key mechanistic insight was obtained and predictions derived therefrom were confirmed experimentally through temperature dependence studies. The computational results have led to the development of electron deficient N-allylhydrazones capable of reacting under mild reaction conditions. Application of the rearrangement to form a new sp3 stereogenic center is reported for the first time.
本文报告了使用密度泛函理论计算对N-烯丙基肼的[3,3]-sigmatropic重排的计算分析。通过温度依赖性研究,获得了关键的机理见解,并证实了由此得出的预测。计算结果促进了电子不足的N-烯丙基肼的开发,使其能够在温和的反应条件下反应。首次报道了应用重排形成新的sp3立体中心。
