The synthesis and resolution of 3,3%-bis(benzyloxy)-1,1%-binaphthalene-2,2%-diol 1 is described. A diastereomeric mixture of 7 (derived from (±)-1 and Boc-Ala-OH) was separated using crystallization and column chromatography.
## 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
## The title compound was found to exhibit confortnaGona1 polymorphism which greatly injluenced the eficiency of the thermorearrangement to 2,2'-bis-S-(N,N-dbnethylthiocarbamato)-lJ'-bi~hthalene. Recognition of this phenomenon has allowed a reproducible synthesis of I,l'-bbtaphthalene-2.2'-dithiol.
