Ethyl 1-[3-(2-oxopyrrolidin-1-yl)prop-yl]-2-phenyl-1H-benzimidazole-5-carboxyl-ate.

ABSTRACT: In the title compound, C(23)H(25)N(3)O(3), the benzimidazole ring system is essentially planar [maximum deviation = 0.0240 (18) Å]. The mean plane through this ring system forms a dihedral angle of 42.23 (7)° with the benzene ring. The pyrrolidine ring is in an envelope conformation with the flap atom disordered over two sites with occupancies of 0.813 (11) and 0.187 (11). In the crystal, weak C-H⋯O hydrogen bonds form R(2) (2)(10) ring motifs, which are connected by further C-H⋯O inter-actions, forming ribbons along the b axis. The crystal structure is further stabilized by weak π-π inter-actions involving the imidazole and benzene rings of the benzimidazole ring system [centroid-centroid distances = 3.6788 (11) and 3.6316 (10) Å] and weak C-H⋯π inter-actions.

Project description:The asymmetric unit of the title compound, C(24)H(27)N(3)O(4), contains two mol-ecules, A and B. The benzimidazole rings are essentially planar [maximum deviations = 0.0144?(10) and 0.0311?(8)?Å in A and B, respectively]. The dihedral angle between the benzimidazole mean plane and its attached benzene ring is 36.90?(5) ° for mol-ecule A and 51.40?(5) ° for mol-ecule B. In both mol-ecules, the pyrrolidine ring adopts an envelope conformation with a C atom as the flap. In molecule B, the flap C atom is disordered over two positions in a 0.711?(6):0.289?(6) ratio. In the crystal, C-H?O inter-actions link the mol-ecules, generating [100] chains. The crystal packing also features weak ?-? inter-actions between the imidazole and benzene rings [centroid-centroid distances = 3.8007?(7) and 3.8086?(7)?Å] and between the benzene rings [centroid-centroid distance = 3.7001?(7)?Å] and C-H?? inter-actions involving the benzene rings.

Ethyl 2-[4-(morpholin-4-yl)phen-yl]-1-[3-(2-oxopyrrolidin-1-yl)prop-yl]-1H-1,3-benzimidazole-5-carboxyl-ate monohydrate.

Project description:The asymmetric unit of the title compound, C(27)H(32)N(4)O(4)·H(2)O, contains two independent benzimidazole-5-carboxyl-ate mol-ecules and two water mol-ecules. In both main mol-ecules, the pyrrolidine rings are in an envelope conformation with a methyl-ene C atom as the flap. The morpholine rings adopt chair conformations. Both benzimidazole rings are essentially planar, with maximum deviations of 0.008?(1)?Å, and form dihedral angles of 37.65?(6) and 45.44?(6)° with the benzene rings. In one mol-ecule, an intra-molecular C-H?O hydrogen bond forms an S(7) ring motif. In the crystal, O-H?O and O-H?N hydrogen bonds connect pairs of main mol-ecules and pairs of water mol-ecules into two independent centrosymmetric four-compoment aggregates. These aggregates are connect by C-H?O hydrogen bonds leading to the formation of a three-dimensional network, which is stabilized by C-H?? interactions.
