Abstract

CD spectra of diastereomeric α-arylethylamides 2,3, 4,5 and 6,7 exhibit nearly enantiomorphic CD curves. Interchromophoric charge-transfer interaction between the aromatic and the amide chromophore is observed only in the amide nπ* band region. MM2 calculations suggest that in the lowest-energy conformer of all diastereomeric pairs the aromatic rings as the major chromophores have mirror image positions relative to the plane defined by the amide-lactone chromophoric system.
