Abstract
Alkylation of thiacalix[4]arenes with ethyl bromoacetate led to high yields (approximate to 60%) of corresponding tetraacetates in various conformatio ns (cone, partial cone, 1,3-alternate) depending strictly on the carbonate (Na, K, Cs) used for the reaction. The complexation ability of new compound s was studied by H-1 NMR.
