In the title compound, C30H27N3O6, the furan and pyrrolidine rings adopt envelope conformations (with C and N atoms as the flaps, respectively). The piperidine ring is in a distorted boat conformation. The β-lactam ring is planar [maximum deviation = 0.0044 (16) Å] and forms dihedral angles of 30.61 (9) and 85.51 (9)°, respectively, with the attached methoxyphenyl and phenoxy rings. The crystal packing is stabilized by N—H⋯O and C—H⋯O interactions forming R22(8), R22(20) and R22(14) ring motifs. The is further consolidated by weak C—H⋯π interactions.

A mixture of methyl 2-(hydroxy(1-(4-methoxyphenyl)-4-oxo-3-phenoxyazetidin -2-yl)methyl)acrylate (1 mmol), isatin (1 mmol) and sarcosine (1 mmol) was refluxed in methanol until completion of the reaction was evidenced by TLC analysis. After completion of the reaction the solvent was evaporated under reduced pressure. The reaction mixture was dissolved in ethyl acetate and washed with water followed by brine solution. The organic layer was separated and evaporated under reduced pressure. The crude mixture was purified by
using ethyl acetate and hexane as (4: 6). The product was dissolved in chloroform and heated for two minutes. The resulting solution was subjected to crystallization by slow evaporation of the solvent for 48 h resulting in the formation of single crystals.The H atoms were positioned geometrically with N—H = 0.86 Å and C—H = 0.93, 0.96, 0.97 and 0.98 Å for aryl, methyl, methylene and methyne H atoms, respectively, and constrained to ride on their parent atoms, with Uiso(H) = 1.5Ueq(methyl C) or 1.2Ueq(non-methyl C/N).
β-Lactam based antibiotics have been successfully used in the treatment of infectious diseases for many years (Jones et al., 1989). The biological activity of β-lactams is mostly believed to be associated with the chemical reactivity of their β-lactam ring and its substituents, especially at the nitrogen of the 2-azetidinone ring (Mehta et al., 2010). The most commonly used β-lactam antibiotics for the therapy of infectious diseases are penicillin and (Brakhage, 1998). In view of potential applications, the determination of the title β-lactam derivative was carried out which is reported in this article.
In the title molecule (Fig. 1), the β-lactam ring makes dihedral angles 30.61 (9)° and 85.51 (9)°, respectively, with the attached methoxyphenyl and phenoxy rings. The furan (O4/C17/C18/C19/C20) and pyrrolidine (C19/C18/C28/C29/N3) rings adopt with C18 and N3 atoms deviating by -0.2044 (13) Å and 0.2529 (13) Å, respectively, from the planes formed by the remaining atoms of the rings. The pyridine ring adopts a distorted boat conformation with atoms C19 and N2 deviating by 0.0932 (12) Å and 0.1741 (14) Å, respectively, from the least-squares plane defined by the remaining atoms (C18/C21/C22/C27) in the ring. The bond lengths and bond angles in the title compound agree with the corresponding bond lengths and angles reported for a closely related compound (Arun et al., (2003).
The crystal packing is stabilized by N—H···O, C—H···O interactions and further consolidated by weak C—H···π interaction. H-atoms bonded to N2, C12 and C16 are involved in hydrogen bonding with atoms O6, O5 and O2 (Fig 2. and Table 1) which connect the molecules forming cyclic centrosymmetric dimers in graph set motifs: R22(8), R22(20) and R22(14), respectively, (Bernstein et al., 1995).

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. |

β-Lactam based antibiotics have been successfully used in the treatment of infectious diseases for many years (Jones et al., 1989). The biological activity of β-lactams is mostly believed to be associated with the chemical reactivity of their β-lactam ring and its substituents, especially at the nitrogen of the 2-azetidinone ring (Mehta et al., 2010). The most commonly used β-lactam antibiotics for the therapy of infectious diseases are penicillin and cephalosporins (Brakhage, 1998). In view of potential applications, the crystal structure determination of the title β-lactam derivative was carried out which is reported in this article.
In the title molecule (Fig. 1), the β-lactam ring makes dihedral angles 30.61 (9)° and 85.51 (9)°, respectively, with the attached methoxyphenyl and phenoxy rings. The furan (O4/C17/C18/C19/C20) and pyrrolidine (C19/C18/C28/C29/N3) rings adopt envelope conformation with C18 and N3 atoms deviating by -0.2044 (13) Å and 0.2529 (13) Å, respectively, from the planes formed by the remaining atoms of the rings. The pyridine ring adopts a distorted boat conformation with atoms C19 and N2 deviating by 0.0932 (12) Å and 0.1741 (14) Å, respectively, from the least-squares plane defined by the remaining atoms (C18/C21/C22/C27) in the ring. The bond lengths and bond angles in the title compound agree with the corresponding bond lengths and angles reported for a closely related compound (Arun et al., (2003).
The crystal packing is stabilized by N—H···O, C—H···O interactions and further consolidated by weak C—H···π interaction. H-atoms bonded to N2, C12 and C16 are involved in hydrogen bonding with atoms O6, O5 and O2 (Fig 2. and Table 1) which connect the molecules forming cyclic centrosymmetric dimers in graph set motifs: R22(8), R22(20) and R22(14), respectively, (Bernstein et al., 1995).
