2-(2-Hydroxyaryl)imidazolidines were synthesized by reaction of aromatic carbonyl compounds with N,N′-dialkylethylenediamines. The title compounds were also prepared using the corresponding Schiff bases instead of carbonyl compounds. Phosphorylation of 2-(2-hydroxyphenyl)imidazolidines with phosphoryl and phosphorothioyl chlorides and phosphorochloridites was accomplished. The reaction of O-phosphorylsalicylaldehyde

Thiophosphorylated derivatives of meta- and ortho-hydroxybenzaldehydes take part in one-step, acid-catalyzed condensations with resorcinol and its derivatives. As a result, new calix[4]resorcinols, which contain four 2-thioxo-1,3,2-dioxaphosphorinane fragments on the aromatic substituents of the calixarene matrix, have been synthesized. In this case, macrocyclic products are formed as rccc- (cone or boat conformation) and/or rctt- (chair conformation) diastereomers, the ratio of which depends on the structure of the starting reagents. The obtained products have been isolated and their structures determined by NMR methods and single-crystal X-ray diffraction. The spectral differences of conformational isomers of the prepared macrocycles have been demonstrated. (C) 2014 Elsevier Ltd. All rights reserved.
