## Abstract Asymmetric catalytic activity of the chiral spiroborate esters **1**–**9** with a O~3~BN framework (see __Fig. 1__) toward borane reduction of prochiral ketones was examined. In the presence of 0.1 equiv. of a chiral spiroborate ester, prochiral ketones were reduced by 0.6 equiv. of bor
