Modification of BINOL units has been well examined via Rh-catalyzed C–H activation and functionalization reactions by using ester carbonyls as directinggroups and alkenes as coupling partners. The one-pot strategy was an efficient protocol for the rapidsynthesis of BINOL derivatives with retention of optical purity.
An efficient microbial resolution of 2,2′-dihydroxy-1,1′-binathyl has been achieved by exposing the corresponding dibutyrate to Bacillus sp; the importance of the size of the ester group for hydrolysis rate and selectivity is emphasized.
