✦ Synopsis

During a study of the motion of rings involved in polymer main chains, we were forced to reveal the configurations of dimethyl cyclohexanone-2,6dipropionate (k) and diethyl cyclohexane-1,3-dipropionate (2). According to the method of Stork et al. 1) Q) was prepared, from which (2) was derived by the Huang-Minlon process 2) and subsequent alcoholysis with ethanol. We wish to report here the stereochemistry of (,&) and (&) determined by "C NMR spectroscopy.
