ABSTRACT
In the title compound, C(26)H(31)NO(4), a sinomenine derivative, the angle between the two aromatic rings is 53.34â (4)°. The N-containing ring is in a chair conformation, while the other two non-planar rings are in a half-boat conformation. In the crystal, mol-ecules are linked by O-Hâ¯N inter-actions into a C(8) chain along [100].
ABSTRACT
The title compound, C(26)H(30)ClNO(4), a sinomenine derivative, has five six-membered rings, two of which are aromatic, with a dihedral angle of 34.13â (20)° between these. The N-containing ring and the fourth ring exhibit chair conformations, while the fifth ring approximates an envelope conformation. A single inter-molecular O-Hâ¯N hydrogen-bonding inter-action gives a one-dimensional chain structure which extends along the a axis. The absolute configuration for the mol-ecule has been determined.
ABSTRACT
In the title sinomenine derivative, C(26)H(28)FNO(4)·1.5H(2)O, the dihedral angle between the two aromatic rings is 55.32â (6)°. The N-containing ring has an approximate chair conformation, while other two rings have approximate envelope and half-chair conformations. One water mol-ecule is located on a twofold symmetry axis. In the crystal, the water mol-ecules form O-Hâ¯O and O-Hâ¯N hydrogen bonds, bridging symmetry-related main mol-ecules.
