Arctigenin: a lignan from Arctium lappa

The title compound {systematic name: (3R-trans)-4-[(3,4-dimethoxy­phen­yl)meth­yl]-3-[(4-hydr­oxy-3-methoxy­phen­yl)meth­yl]-4,5-dihydrofuran-2(3H)-one}, C(21)H(24)O(6), has a dibenz­yl­butyrolactone skeleton. The two aromatic rings are inclined at a dihedral angle of 68.75 (7)° with respect to each...

description The title compound {systematic name: (3R-trans)-4-[(3,4-dimethoxy­phen­yl)meth­yl]-3-[(4-hydr­oxy-3-methoxy­phen­yl)meth­yl]-4,5-dihydrofuran-2(3H)-one}, C(21)H(24)O(6), has a dibenz­yl­butyrolactone skeleton. The two aromatic rings are inclined at a dihedral angle of 68.75 (7)° with respect to each other. The lactone ring adopts an envelope conformation. A series of O—H⋯O and C—H⋯O hydrogen bonds contribute to the stabilization of the crystal packing. The absolute configuration was assigned on the basis of the published literature.
