We present here a highly efficient NHC‐catalyzed kinetic resolution of a wide range of 1,1′‐biaryl‐2,2′‐diols and amino alcohols to provide them in uniformly ≥99 % ee . This represents the first highly enantioselective catalytic acylation of axially chiral alcohols. The aldehyde backbone that is incorporated into the chiral acyl azolium intermediate was found to have a significant effect on the enantioselectivity of the process.
