Synthesis and antioxidant activity of novel 15-alkyl/aryl-13, 17-dihydro-15λ~5-dibenzo [e, k] [1, 3, 7, 10, 2] dioxadiazaphosphacyclotridecin-15-selones/thiones/ones

摘要

A 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 N_2 atmosphere in THF. All the title compounds were confirmed by analytical and spectral data (IR, ~1H-, ~(13)C-, ~(31)P-NMR, and mass). The title compounds exhibited promising anti-oxidant activity.
