| Abstract
| - The crystalline inclusion complexes of cholic acid with three symmetric N-aryl-N-nitrosamines wereprepared, and their X-ray structures were solved. As a result of chiral conformations adopted bythe enclathrated guest nitrosamines, the solid-state CD spectra were measured in KBr disks. Theobserved Cotton effect sign, corresponding to the n−π* transition, was correlated with the helicityof the twisted nitrosamine chromophore conjugated with the N-aryl substituent. In addition, theabsolute configuration of the enantiomorphous crystals of N-benzyl-N-nitroso-4-chloroaniline wasestablished on the basis of the solid-state CD and X-ray crystallographic results.
