In the title compound, C29H23NO2, the pyrrolidine ring adopts a twisted conformation about one of the C—N bonds. The acenaphthone ring (r.m.s. deviation = 0.025 Å) lies almost perpendicular to the pyrrolidine ring [dihedral angle = 88.08 (8)°]. The dihedral angle between the phenyl rings is 88.12 (11)°. In the weak C—H⋯π interactions connect the molecules.

A mixture of chalcone [1,3-diphenyl-2-propen-1-one] (0.40 g, 2 mmol), acenaphthenequinone (0.36 g, 2 mmol), sarcosine (0.17 g, 2 mmol) and methanol (25 ml) was heated for four hours using oil bath using a dimmerstat at a temperature of 40° C. The reaction mixture was cooled to room temperature and poured into ice-cold water. The solid mass obtained was filtered, washed with water, dried and colourless blocks of (I) were obtained by recrystallization using acetone as solvent by slow evaporation method.
H atoms were positioned geometrically and refined using riding model,with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C) for aromatic C—H, C—H = 0.97 Å and Uiso(H) = 1.2Ueq(C) for CH2, C—H = 0.96 Å and Uiso(H) = 1.5Uiso(C) for CH3.
1,3-dipolar cycloadditions using
is conceptually the most simple and efficient method for the construction of saturated, nitrogen containing five-membered heterocycles (Padwa, 1984). Ylide generation, often performed in situ (Grigg, 1987), followed by with suitable dipolarophiles furnishes pyrrolidines and pyrroles in only one step from simple starting materials (Huisgen, 1988). 1,3-dipolar cycloadditions of with olefinic and acetylenic dipolarophiles represent an important approach for the formation of pyrrolidines and pyrrolizines which are prevalent in a variety of biologically active compounds (Bridges et al., 1993). In view of this we have determined the structure of the title compound.In the title compound C29H23NO2, the C—O bond distance (1.21 Å) of the carbonyl group in the benzoyl moiety indicates n-p overlap. The bond angles and dihedral angle of C9—C12—C1 (101.69 Å) of the acenapthone ring indicate it to be in a plane nearly perpendicular to the pyrrolidine ring. The sum of the angles around N-atom of the pyrrolidine ring accounts for 338.78°. This indicates that the structure approaches pyramidal shape. The study of torsion angle, asymmetry parameters and least-square plane calculation shows that the pyrrolidine ring adopts a φ = 333.0 (3)° (Cremer & Pople, 1975). The Pseudorotation parameter P and τ are 136.4 (1)° and 43.71 (1)° respectively (Rao et al., 1981) showing that C15 and N1 are twisted and puckered.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |

1,3-dipolar cycloadditions using azomethine ylides is conceptually the most simple and efficient method for the construction of saturated, nitrogen containing five-membered heterocycles (Padwa, 1984). Ylide generation, often performed in situ (Grigg, 1987), followed by cycloaddition with suitable dipolarophiles furnishes pyrrolidines and pyrroles in only one step from simple starting materials (Huisgen, 1988). 1,3-dipolar cycloadditions of azomethine ylides with olefinic and acetylenic dipolarophiles represent an important approach for the formation of pyrrolidines and pyrrolizines which are prevalent in a variety of biologically active compounds (Bridges et al., 1993). In view of this we have determined the structure of the title compound.
In the title compound C29H23NO2, the C—O bond distance (1.21 Å) of the carbonyl group in the benzoyl moiety indicates n-p overlap. The bond angles and dihedral angle of C9—C12—C1 (101.69 Å) of the acenapthone ring indicate it to be in a plane nearly perpendicular to the pyrrolidine ring. The sum of the angles around N-atom of the pyrrolidine ring accounts for 338.78°. This indicates that the structure approaches pyramidal shape. The study of torsion angle, asymmetry parameters and least-square plane calculation shows that the pyrrolidine ring adopts a envelope conformation and puckered, Q2 = 0.4030 (18) Å, φ = 333.0 (3)° (Cremer & Pople, 1975). The Pseudorotation parameter P and τ are 136.4 (1)° and 43.71 (1)° respectively (Rao et al., 1981) showing that C15 and N1 are twisted and puckered.
The crystal structure is stabilized by weak C—H···π interactions.
