چکیده
Cork smoker wash solids (black wax) that is obtained in the process of making corkboard by treating ground cork with superheated steam useless waste, generating environmental problems. On other hand, black wax a rich source friedelin (1) and 3-hydroxyfriedel-3-en-2-one (3), pentacyclic triterpenoids belonging to friedelane family. In present work, simple, fast, efficient procedure for extraction highly purified from presented. Extraction hexane or acetone afforded mixture 3-hydroxyfriedel-3-en-2-one. However, chromatographic separation 1 3, due their very similar Rf coefficients, difficult, especially on multigram scale. Therefore, conversion an acetyl derivative 4 was proposed acetylation above mixture. Appropriate selection eluent sequence allows rapid resulting 4.

The title compound, C(13)H(17)NO(2), has an intra-molecular N-H⋯O hydrogen bond, forming a planar six-membered ring with a mean deviation of 0.015 (5) Å from the plane. This plane makes a dihedral angle of 7.19 (8)° with the adjacent phenyl ring. Through an inter-molecular O-H⋯O hydrogen bond, the mol-ecules with their 2(1) screw and b-translation equivalents form a helical chain running parall...

The title enamino ketone, C(12)H(15)NO, a derivative of 4-(phenyl-amino)-pent-3-en-2-one, presents a roughly planar [greatest displacement of an atom from the pentenone plane is 0.033 (2) Å] pentenone backbone, enhanced by an intra-molecular N-H⋯O hydrogen bond; the asymmetry in C-C distances in the group suggests the presence of unsaturated bonds. The overall geometry in the free ligand differ...

In the title compound, C(17)H(17)NO(2), the dihedral angle between the two benzene rings is 55.2 (2)°. The meth-oxy group is slightly twisted away from the aniline ring [dihedral angle = 10.3 (2)°]. An intra-molecular N-H⋯O inter-action is present. In the crystal, the mol-ecules are linked into a three-dimensional supra-molecular network through two sets of C-H⋯π inter-actions.
