Here, we present a highly enantioselectivesynthesis of 1,2-amino alcoholsfrom readily available racemic 1,2-diols through a borrowinghydrogen process. An intriguing acid effect was discovered for this Ru-catalyzed amination reaction, which led to a significant improvement of the stereoselectivity of the process. Preliminary mechanistic studies suggest a scenario of Brønsted acid-assisted dynamic
