✦ Synopsis

The stereoisomerism of some methyl-substituted 1,3,2-dioxathiepanes has been investigated by I3C and * '0 NMR spectroscopy. The effects of substituents on the conformational equilibria of the seven-membered rings are discussed and compared with those for six-membered ring sulphites.

## Abstract The influence of substituents in a new series of 2__H__‐thiopyrans, 2__H__‐thiopyran‐2‐ones (thiones) and their thiazine analogues is examined by means of carbon (^13^C) and nitrogen (^15^N) NMR. A linear relationship is shown to exist between the chemical shifts (δ~13C~ or δ~15N~) of t
