Sažetak
Stereochemistry of the titled compounds was determined by X-ray structure analysis. The seven-membered lactam rings of both compounds are in a quasi-chair conformation which agrees
with the lactam rule. The mean values of the C-NH-CO-C torsion angles are -6 ° and +5°, respectively, and these values
also agree with Klyne's hypothesis.
