The first catalytic enantioselective aminolysis of trans ‐2,3‐epoxy alcohols has been accomplished. This stereospecific ring‐opening process was efficiently promoted by a tungsten/bis(hydroxamic acid) catalytic system, furnishing various anti ‐3‐amino‐1,2‐diols with excellent regiocontrol and high enantioselectivities (up to 95 % ee ). Moreover, virtually enantiopure 3‐amino‐1,2‐diols could be obtained by the sequential combination of two reactions that both involve the use of a chiral catalyst.
