Abstract

The syn-atropisomers of the title bis(tertiary amide)s were designed as six-bladed molecular propellers based on the “directing effects” of amide dipoles; the helicity of the propeller is biased to prefer one handedness upon the attachment of point chirality to the amide nitrogens to attain stronger circular-dichroism activity than for the non-propeller-shaped anti-isomers.
