## Abstract An economic and practical method for preparing enantiomerically pure [1,1′‐binaphthalene]‐2,2′‐diols is reported. Thus, a condensate of __threo__‐(1__S__,2__S__)‐2‐amino‐1‐(4‐nitrophenyl)propane‐1,3‐diol and cyclohexanone (CHANP) was used as a resolving agent. A 2 : 1 : 1 mixture of rac
