Circular dichroism and absolute stereochemistry of
Enantiopure [8]paracyclophane-10-carbonitrile (1) and related compounds were prepared. The absolute stereochemistry of [CD(+)242.0]-1 was determined to be R by theoretical calculation of its CD spectrum using the pi-electron SCF-CI-DV MO method. The theoretical determination came to the same conclusion as the X-ray crystallographic method had previously given. Other related compounds show similar CD spectra leading to the R absolute stereochemistry.
