Two new types of 1,3,2-oxaborolidines were prepared from (1S,2S)-2- amino-1-(4-nitrophenyl)-propane-1,3-diol and used as catalysts in the asymmetric reduction of acetophenone. The influence of temperature as well as the effect of the structure of catalyst on the enantioselectivity is discussed. The origin of the products' configurational is explored.
