It has been suggested that the sign of the circular dichroism (CD) maximum (C=O at 220-230 run) of the Y-lactones might be determined by the two factors. That is, configuration at C-2 (1) (2-(S)-configuration gave positive sign and 2-(R)-configuration gave negative sign) and the conformation of the
## Abstract The correlation between the puckering angle of the four‐membered cycle and ^4^__J__ has been obtained from analysis of the PMR spectra of some 2‐substituted azetidines and oxetanes. The absolute values of ^4^__J__~cis~ and ^4^__J__~__trans__~ were found to decrease with decreasing of th
