Abstract

Abstract: To determine the absolute configuration and conformation of chiral acyclic 1, 3- glycols, the CD exciton chirality method has been applied to various acyclic 1, 3-diesters with p-bromobenzoate, p-chlorobenzoate, or benzoate chromophore. Acyclic anti-l, 3- dibenzoates exhibit typical exciton split CD Cotton effects, the sign of which agrees with the sign of the screw sense between two benzoate chromophores in the conformation ...
