Two lipophilic calixarenes, derived from resorcinol (R1) and pyrogallol (R2), were investigated as receptors for pyrimidine and xanthine bases in extraction experiments. Extraction abilities sequence for R1 in chloroform is: cytosine>uracil>thymine, whereas for R2: thymine>uracil>cytosine. Among pyrimidine bases, no clear pattern of extraction was observed: uracil was extracted most effectively to toluene phase, thymine - into diethyl sebacate, cytosine into - chloroform.
