Abstract: | Crystal and molecular structures of the title compounds 1b and 1c have been determined by the X-ray method. Crystals of 1b are monoclinic, space group P21/c, and crystals of 1c are orthorhombic, space group P212121. The sulfinyl oxygen atom and the alkoxycarbonyl group in both compounds are trans oriented, and the six-membered rings adopt a sofa conformation. The differences between conformation, bond lengths, and angles in the compounds investigated are discussed. © John Wiley & Sons, Inc. |
