The first chiral disulfinyldithiacalixarenes have been obtained by oxidation of two adjacent epithio groups of the tetramethyl ether of tetra(p- tert-butyl)tetrathiacalixarene. The chiral resolution was achieved by HPLC using Chiralpak AD as a stationary phase. Furthermore, the absolute configuration of these compounds was determined by X-ray crystallography.
