Crystal structure of Dehydrodieugenol B methyl ether, a neolignan from Nectandra leucantha Nees and Mart (Lauraceae)
2018
In the title compound, C21H24O4 (systematic name: 4,5′-diallyl-2,2′,3′-trimethoxydiphenyl ether), the aromatic rings lie almost perpendicular to each other [dihedral angle = 85.96 (2)°]. The allyl side chains show similar configurations, with Car—C—C=C (ar = aromatic) torsion angles of −123.62 (12) and −115.54 (12)°. A possible weak intramolecular C—H⋯O interaction is observed. In the crystal, molecules are connected by two C—H⋯O hydrogen bonds, forming undulating layers lying parallel to the bc plane. Weak C—H⋯π and π–π stacking interactions also occur.
