Thiacalix[4]arenes mono-, 1,3-di-, tri-, and tetrasubstituted at the lower rim, including those containing different substituents, were synthesized by the method based on the ability of the phenacyl moiety to serve as the protecting group, as well as to b

Two different 1, 3-Distal thiacalix[4]arenas were prepared by the reaction of thiacalix[4]arene with phenacyl and/or p-nitro phenacyl bromide in acetone or acetonitrile in the presence of dry CsOH. The prepared 1, 3-distal disubstituted thiacalixarenes afforded two pairs of diastereomers upon brominating in chloroform. The obtained diastereomers were separated by fractional crystallization in a mixture dichloromethane-acetone.
