2-(2-Hydroxyphenyl)imidazolidines and their O-phosphorylated derivatives

Abstract

© 2017, Pleiades Publishing, Ltd. 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 with N,N′-dialkylethylenediamines also afforded 2-(2-hydroxyphenyl)imidazolidines.
