(S)-5-Hexyl-1-[(S)-2-hydr-oxy-1-phenyl-ethyl]-4-meth-oxy-1H-pyrrol-2(5H)-one.

ABSTRACT: The title compound, C(19)H(27)NO(3), was obtained by the reaction of (3S,7aR)-7a-hexyl-7-meth-oxy-3-phenyl-2,3-dihydro-pyrrolo[2,1-b]oxazol-5(7aH)-one and triethyl-silane using titanium(IV) chloride as catalyst. In the mol-ecule, the phenyl and dihydro-pyrrolone rings form a dihedral angle of 83.8?(1)°. O-H?O hydrogen-bonding inter-actions lead to the formation of a chain parallel to the a axis.

4-[(5-Hydr-oxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)phenyl-meth-yl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one ethanol hemisolvate.

Project description:The asymmetric unit of the title compound, C(27)H(24)N(4)O(2)·0.5C(2)H(6)O, comprises two crystallographically independent mol-ecules (A and B) with slightly different conformations, and one ethanol mol-ecule of crystallization. Intra-molecular C-H⋯O and O-H⋯O hydrogen bonds generate six- and eight-membered rings, producing S(6) and S(8) ring motifs, respectively. In mol-ecule A, one of the benzene rings is disordered over two positions, with site-occupancy factors of 0.542 (11) and 0.458 (11). The dihedral angles between the central benzene ring and the two outer benzene rings are 73.88 (9) and 82.6 (2)/88.9 (2)° in mol-ecule A, and 80.81 (8) and 79.38 (8)° in mol-ecule B. In the crystal structure, mol-ecules form infinite one-dimensional chains in the (101) plane. The crystal structure is stabilized by inter-molecular O-H⋯N, N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds, weak C-H⋯π and π-π [centroid-centroid = 3.5496 (1) Å] inter-actions.

3-Benzamido-1-benzoyl-1H-pyrrol-2(5H)-one.

Project description:In the title compound, C(18)H(14)N(2)O(3), one of the phenyl rings is almost coplanar with the pyrrole ring [dihedral angle = 2.56 (14)°], whereas the other one is tilted by 63.01 (6)° with respect to the pyrrole ring. Since the NH group is shielded from possible acceptors, this group is not involved in hydrogen bonding.

4-[(4-Chloro-phen-yl)(5-hydr-oxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)meth-yl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one.

Project description:In the the title compound, C(27)H(23)ClN(4)O(2), the chloro-phenyl ring forms dihedral angles of 77.70 (9) and 86.65 (9)°, respectively, with the pyrazol-3-one and pyrazole rings. The phenyl rings attached to the pyrazole rings are twisted away from them [dihedral angles 33.80 (9) and 40.34 (10)°]. An intramolecular O-H⋯O hydrogen bond generates an S(8) ring motif. The mol-ecules are linked into chains running along the c axis by N-H⋯N hydrogen bonds, and the chains are cross-linked via C-H⋯O hydrogen bonds and C-H⋯π inter-actions involving the chloro-phenyl ring.
