The three conformations of 5,11,17,23-tetra-tert-butyl-25,26,27,28-tetrakis[(benzoyl)methoxy]-2,8,14, 20-tetrathiacalix[4]arene 1: cone, partial cone and 1,3-alternate, were prepared by the treatment of 5,11,17,23-tetra-tert-butyl-2,8,14,20-tetrathiacalix

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.
