The stereoisomers of 1,3-dithiane 1,3-dioxides. Preparation, configuration and some conformational aspects
Abstract
Oxidation of 1,3-dithiane with different oxidizing agents gave the 1,3-dithiane cis- and trans-1,3-dioxides 1 and 2. Their configuration and the conformational preferences of the sulphinyl oxygen atom have been determined by NMR spectroscopy and by X-ray analyses.
