(Received 5 June 2009; accepted 26 June 2009; online 11 July 2009)

In the title compound, C25H25NO3, the dihydro­pyran ring adopts a half-chair conformation, whereas the pyrrolidine ring is in a twist conformation. The tolyl group is oriented at an angle of 82.92 (7)° with respect to the napthalene ring system. In the crystal structure, mol­ecules are linked into centrosymmetric dimers by C—H⋯π inter­actions involving the benzene ring of the tolyl group.

Chromenopyrrole compounds are used in the treatment of impulsive disorders (Caine, 1993), aggressiveness (Tidey & Miczek, 1992), parkinson's disease (Carlson, 1993), psychoses, memory disorders (Sokoloff et al., 1990), anxiety and depression (Wilner, 1985). Pyrrole derivatives have good in vitro activities against mycobacteria and candidae (Biava et al., 2005). These derivatives also possess anti-inflammatory (Fernandes et al., 2004) and antiviral (Borthwick et al., 2000) activities. It has also been shown that N–substituted pyrrole derivatives inhibit human immuno deficiency virus type-I (HIV-I) (Jiang et al., 2004). In view of its medicinal importance, the crystal structure determination of the title compound was undertaken.

The geometric parameters of the title molecule (Fig. 1) agree well with those reported for a similar structure (Gunasekaran et al., 2009). The sum of bond angles around atom N1 (334.0°) is in accordance with sp3 hybridization. The napthalene ring system (C2-C11) and the tolyl group (C16-C22) are oriented at an angle of 82.92 (7)° with respect to each other. The heterocyclic ring (O1/C1/C2/C11-C13) of the chromenopyrrole unit adopts a half-chair conformation, with puckering parameters Q = 0.462 (2) Å, θ = 49.3 (2)° and ϕ = 261.2 (2)° (Cremer and Pople, 1975). The pyrrolidine ring (N1/C1/C13-C15) adopts a twist conformation, with puckering parameters of q2 = 0.485 (1) Å and ϕ = 16.2 (2)° (Cremer and Pople, 1975).

The crystal packing is stabilized by weak intermolecular C—H···π [C22—H22A···Cg1; Cg1 is the centroid of the C16—C21 ring] interactions (Table 1).

Experimental top

A mixture of (Z)-methyl 2-((1-formylnaphthalen-2-yloxy)methyl)-3- p-tolylacrylate (20 mmol) and sarcosine (30 mmol) was refluxed in benzene for 20 h and the solvent was removed under reduced pressure. The crude product was subjected to column chromatography to get the pure product. A chloroform and methanol (1:1) solvent mixture was used for the crystallization under slow evaporation method.

Refinement top

H atoms were placed in idealized positions and allowed to ride on their parent atoms, with C-H = 0.93, 0.98, 0.97 and 0.96 Å for aromatic, methine, methylene and methyl H respectively, and Uiso(H) = 1.5Ueq(C) for methyl H and Uiso(H) = 1.2Ueq(C) for all other H atoms.

Special details top

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.
