General description
6,6′-Dibromo-1,1′-bi-2-naphthol is a 1,1′-bi-2-naphthol derivative. Vibrational circular dichroism (VCD), electronic circular dichroism (ECD) and optical rotatory dispersion (ORD) spectra for the enantiomers of 6,6′-dibromo-1,1′-bi-2-naphthol have been evaluated.

The experimental vibrational circular dichroism (VCD), electronic circular dichroism (ECD), and optical rotatory dispersion (ORD) spectra for both enantiomers of 6,6'-dibromo-1,1'-bi-2-naphthol have been measured. The corresponding quantum chemical predictions for three different orientations of hydroxyl groups in this molecule were

A novel binuclear chiral zirconium catalyst was successfully used in enantioselective Strecker reactions. The catalyst was readily prepared from zirconium t-butoxide (Zr(OtBu)4), (R)-6,6'-dibromo-1, 1'-bi-2-naphthol ((R)-6-Br-BINOL), and (R)-3,3'-dibromo-1, 1'-bi-2-naphthol ((R)-3-Br-BINOL) to form unique binuclear structure. It was revealed that a combination
