摘要：

The assignment of the cis and trans configuration of 3,4-dimethyl-6-t-butyl-5,6-dihydro-2H-thiopyran-S-oxides and S-Methyl cations is made by C-13 and O-17 NMR, and by force field calculations. It is shown that the preferred conformation of all compounds is the half chair and that a previous configurational assignment of the S-oxides should be reversed.
