Abstract

Induced circular dichroism (ICD) was observed in binaphthyl amides of chiral primary amines. The CDs changed to split curves centered at 225 nm after N-methylation. The calculated screw senses of the two naphthyl groups accorded with those expected from their exciton chiralities, indicating a possible application for determination of absolute configuration.
