## Abstract The first asymmetric reaction catalyzed by chiral spiroborated esters with an O~3~BN framework was reported. In the presence of 0.1 equivalent of (__R,S__)β1 or (__S,S__)β1, acetophenone was reduced by 0.6 equivalent of borne in THF at 0β5 Β°C for 2 h to give (R)β1βphenylethanol of up to
