Abstract:
[reaction: see text] A practical method for the determination of the absolute configuration of aliphatic secondary alcohols, based on the circular dichroism of the readily available N-(1,8-naphthaloyl)-2-aminobenzoyl (NAB) derivative, is presented. The origin of the induced Cotton effects is traced by ab initio calculations to the dominant helicity of the NAB pi-electron system.
