A Practical Method for Resolution of the Optical Isomers of 2,2′-Dihydroxy-1,1′-binaphthalene

Abstract

Inexpensive (R)-(-)-2-aminobutanol is advantageously used for resolution of the optical isomers of 1,1′-binaphthalene-2,2′-diyl hydrogen phosphate, thus providing a practical route to both of the highly pure enantiomers of 2,2′-dihydroxy-1,1′-binaphthalene on a preparative scale.
