Abstract
Novel calix[4]resorcinols with four 2-thioxo-1,3,2-dioxaphosphorinane fragments included in aromatic substituents have been synthesized via a one-step condensation of resorcinol and its derivatives with a new para-thiophosphorylated benzaldehyde. It has been found that the diastereomeric ratio depends substantially on the reaction conditions, in particular, the solvents and catalysts used. The macrocyclic products obtained are rctt- and/or rccc-isomers, which were isolated and the structures determined by NMR and single crystal X-ray diffraction studies.
