First Preparation and Structural Determination of Optically Pure Cyclic Polysulfides, 6, 10-Diethyl Trithiolo[h]benzopentathiepin Monooxides
Optically pure cyclic polysulfides, 6,10-diethyl trithiolo[<I>h</I>]benzopentathiepin 7-oxides (<B>4</B>) and (<B>5</B>) were prepared by asymmetric oxidation of 6,10-diethyl trithiolo[<I>h</I>]benzopentathiepin. The structure of <B>4</B> and <B>5</B> was determined by X-ray crystallographic analysis and the configuration was confirmed as <I>R</I> configuration on the sulfinyl sulfur atoms.
