✦ Synopsis

The 13 C and 1 H NMR spectra of the four possible thiolactams of sparteine (1) were recorded and the thiolactam group effects were determined. Most of the effects are greater than those of the lactam group in the oxo analogs. A good linear correlation between the 13 C chemical shifts of CvS and those of CvO was found. The effects could help in assignment of the spectra and determination of conformation of thiolactams and related thiocarbonyl compounds.

## Abstract The ^1^H NMR 270‐MHz spectra of substituted 2‐phenylthiazolidines were recorded and the substituent‐induced chemical shifts (SCS) of the benzylic proton plotted against σ, the correlation coefficient being 0.801 and −ρ = 10.29 Hz. Halogens show deviations in the SCS plots. When the halo
