Synthesis and antioxidant activity of novel 15‐alkyl/aryl‐13, 17‐dihydro‐15λ5‐dibenzo [e, k] [1, 3, 7, 10, 2] dioxadiazaphosphacyclotridecin‐15‐selones/thiones/ones

Abstract

AbstractA new class of phosphorus macrocycles were synthesized from 2‐[(E)‐2‐2 [(hydroxymethyl) phenyl] imino ethylidene) amino] phenyl methanol 1 with various phenylphosphorodichloridates, phenyldichlorophosphine, and ethyldichlorophosphite in the presence of triethylamine at 0–10°C under N2 atmosphere in THF. All the title compounds were confirmed by analytical and spectral data (IR, 1H‐, 13C‐, 31P‐NMR, and mass). The title compounds exhibited promising anti‐oxidant activity. J. Heterocyclic Chem., (2011).
