(2R,5S)-5-Benzyl-2,3-dimethyl-4-oxo-2-phenyl-imidazolidin-1-ium chloride.

ABSTRACT: The title hydro-chloride salt, C(18)H(21)N(2)O(+)·Cl(-), is an imidazolidinone catalyst, which was derived from L-phenyl-alanine through cyclization with acetophenone. The imidazolidinone compound has a five-membered heterocyclic ring including two chiral centres. The imidazolidinone ring displays an envelope conformation, with the flap protonated N atom lying 0.497?(3)?Å above the mean plane of the remaining four atoms. In the crystal structure, one-dimensional supra-molecular chains parallel to the crystallographic 2(1) screw axis are formed by N-H?Cl hydrogen bonds involving the NH(2) (+) and Cl(-) groups. Intra-molecular N-H?Cl inter-actions are also present.

Project description:The title compound, C(30)H(28)N(6)O(2), is a symmetric diimine derived from ortho-dibenzaldehyde. Both C=N bonds are (E)-configured.

In the crystal, C-H?O contacts connect the mol-ecules into chains along the b axis and give rise to a C(1) (1)(14)C(1) (1)(14) and a R(2) (2)(12) pattern on different levels of graph-set analysis. The shortest inter-centroid distance between two centroids was found at 4.2074?(11)?Å between the two five-membered heterocycles.

N-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-di-hydro-1H-pyrazol-4-yl)-2-phenyl-acetamide.

Project description:The title compound, C19H19N3O2, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In mol-ecule A, the pyrazole ring adopts a slightly disordered half-chair conformation while in B it is planar [r.m.s. deviation = 0.0386?(15)?Å]. The dihedral angle between the mean planes of the two phenyl rings is 56.2?(8) in A and 38.2?(3)° in B. The N-phenyl substituent on the pyrazole ring is twisted by 46.5?(2) in A and 58.6?(4)° in B while the extended phenyl ring is twisted by 82.2?(8) in A and 87.5?(9)° in B. The mean plane of the amide group forms an angle of 74.8?(3) in A and 67.7?(1)° in B with respect to the phenyl ring. In addition, the amide group is rotated by 51.4?(1) in A and 53.6?(2)° in B from the the mean plane of the pyrazole ring. In the crystal, the two molecules are linked via N-H?O hydrogen bonds, supported by weak C-H?O inter-actions, forming dimers enclosing an R 2 (2)(10) ring motif. The dimers are linked via C-H?O inter-actions, forming a three-dimensional structure.
