Bis((5-allyl-2-(benzo[<i>d</i>][1,3]dioxol-5-yl)benzofuran-7-yl)oxy)methane: An Unusual <i>Nor</i>-Neolignan Dimer from <i>Magnolia grandiflora</i> L.

Abstract

An unreported and unusual nor-neolignan dimer, namely bis((5-allyl-2-(benzo[d][1,3]dioxol-5-yl)benzofuran-7-yl)oxy)methane (1), was isolated from the bark-derived chloroform extract of Magnolia grandiflora L. Compound 1 was structurally elucidated through the detailed analysis of the spectroscopic data (one- and two-dimensional nuclear magnetic resonance, infrared, and high-resolution mass spectrometry). The effect of compound 1 on the mycelial growth of Fusarium oxysporum was also determined, affording moderate antifungal activity.
