Abstract
Synthesis methods of calix[4]resorcinarenes are known to be based on the tetramerization reactions of aliphatic and aromatic aldehydes with resorcinol and others aromatic phenols in acidic water-alcohol media [1, 2]. We developed a new one-stage synthetic approach to calix[4]resorcinarenes phosphorylated on the lower molecular rim by reaction of resorcinol and its derivatives with available α-phosphorylated acetals and ethoxyvinylphosphonates under the acid catalysis conditions [3–6]. We found that this method can be used to obtain calixarene including dithiophosphate fragments on the lower molecule rim. It is achieved by bringing О,О-diethyl-S-[β-(О,О-diethyl)]ethyldithiophosphate II into the reaction with resorcinol and its derivatives Iа and Ib [7] and by carrying out the process in trifluoroacetic acid.
