The title schulzeine derivative, C22H24N2O4, crystallizes with two crystallographically independent molecules of almost identical conformation in the The tricyclic core of schulzeine has a fused-three-ring system comprising the tetrahydroisoquinoline and δ-lactam moieties. In both molecules, the pyridine ring adopts a twisted-boat conformation, whereas the lactam ring is in a boat conformation. The two methoxy groups are slightly twisted from the attached benzene ring [C—O—C—C torsion angles = −21.3 (2) and −20.5 (2)° in molecule A, and −6.3 (2) and −16.2 (2)° in molecule B] and the benzamide moiety is in a (−)-synclinal conformation with respect to the lactam ring. In the crystal, molecules are linked into V-shaped dimers by intermolecular N—H⋯O hydrogen bonds and weak C—H⋯O interactions. These dimers are stacked into V-shaped columns along the a axis. Adjacent columns are further linked in an antiparallel manner. C—H⋯π interactions are also observed.

The title schulzeine benzamide derivative was synthesized according to the previous reported method (Kuntiyong et al., 2006). Colourless block-shaped single crystals of the title compound suitable for x-ray
were crystallized from hexane:ethylacetate (2:1 v/v) by slow evaporation at room temperature after a few days.All H atoms were placed in calculated positions with d(N—H) = 0.86 Å, d(C—H) = 0.93 Å for aromatic, 0.97 for CH2 and 0.96 Å for CH3 atoms. The Uiso values were constrained to be 1.5Ueq of the
for methyl H atoms and 1.2Ueq for the remaining H atoms. A rotating group model was used for the methyl groups. The highest residual electron density peak is located at 2.33 Å from H21G and the deepest hole is located at 1.38 Å from C5B. A total of 5097 Friedel pairs were merged before final as there is no large for the determination of the absolute configuration.Schulzeine α-glucosidase with IC50 values of 48–170 nM (Melo et al., 2006). The potent α-glucosidase inhibitory activity makes them attractive leads for drug candidate for diseases such as cancer, diabetes and viral infections. During the course of our research on natural product synthesis of schulzeines, the title schulzeine benzamide derivative was synthesized (Kuntiyong et al., 2006). The single-crystal x-ray structural study of the title compound (I) was undertaken in order to gain detailed conformations of the molecular structure.
were isolated from the marine sponge Penares schulzei (Takada et al., 2004). Schulzenine A—C inhibitsThe title compound crystallized with two crystallographically independent molecues A and B in the δ-lactam moieties. In both molecules, the pyridine ring (C5–C9/N1) adopts a twisted boat conformation with puckering parameters Q = 0.6943 (17) Å, θ = 92.19 (14)° and φ = 245.21 (14)° in molecule A [Q = 0.5265 (16) Å, θ = 112.63 (17)° and φ = 263.90 (19)° in molecule B] and the lactam ring (C9–C13/N1/O1) has a standard boat conformation (Cremer & Pople 1975). The two methoxy groups are slightly twisted from the attached benzene ring with the torsion angles C21–O2–C2–C3 = -21.3 (2)° and C22–O3–C4–C3 = -20.5 (2)° in molecule A [the corresponding values are -6.3 (2) and -16.2 (2)° in molecule B]. The benzamide moiety is not planar with the dihedral angle between the mean plane through C14–C15/N2/O4 and C15–C20 benzene ring being 8.97 (9)° in molecule A [8.10 (11)° in molecule B]. The orientation of the benzamide moiety can be described by the torsion angle C14–N2–C12–C13 = -92.77 (17)° in molecule A [-82.56 (18)° in molecule B] which shows the (-)-syn-clinal conformation with respect to the lactam ring. There are two stereogenic centers at atoms C12 and C9 (Fig. 1) or postions 3 and 11b of the tricyclic core of schulzeine. Fig. 1 show that H atoms at C12 and C9 are in cis-relationship. An intramolecular C10A—H10B···O3A weak interaction (Table 1; Fig. 1) generates a S(6) ring motif (Bernstein et al., 1995).
(Fig. 1). These two molecules are almost conformationally identical with slightly different bond lengths and angles. The bond lengths in (I) are within normal ranges (Allen et al., 1987). The tricyclic core of schulzeine (C1–C13/N1/O1) has a fused-three-ring system comprising of the tetrahydro isoquinoline andIn the crystal packing (Fig. 2), molecules are linked into V-shaped dimers by N—H···O hydrogen bonds and C—H···O weak interactions (Table 1) which generate two S(7) ring motifs (Bernstein et al., 1995). These dimers are stacked into V-shaped columns along the a axis. Adjacent columns are further linked by C—H···O weak interactions in an antiparallel manner. C—H···π interactions were also observed (Table 1); Cg1 and Cg2 are the centroid of C1A–C6A and C15A–C20A benzene rings, respectively.

Experimental. The low-temparture data was collected with the Oxford Cyrosystem Cobra low-temperature attachment. |
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. |

Schulzeine alkaloids were isolated from the marine sponge Penares schulzei (Takada et al., 2004). Schulzenine A—C inhibits α-glucosidase with IC50 values of 48–170 nM (Melo et al., 2006). The potent α-glucosidase inhibitory activity makes them attractive leads for drug candidate for diseases such as cancer, diabetes and viral infections. During the course of our research on natural product synthesis of schulzeines, the title schulzeine benzamide derivative was synthesized (Kuntiyong et al., 2006). The single-crystal x-ray structural study of the title compound (I) was undertaken in order to gain detailed conformations of the molecular structure.
The title compound crystallized with two crystallographically independent molecues A and B in the asymmetric unit (Fig. 1). These two molecules are almost conformationally identical with slightly different bond lengths and angles. The bond lengths in (I) are within normal ranges (Allen et al., 1987). The tricyclic core of schulzeine (C1–C13/N1/O1) has a fused-three-ring system comprising of the tetrahydro isoquinoline and δ-lactam moieties. In both molecules, the pyridine ring (C5–C9/N1) adopts a twisted boat conformation with puckering parameters Q = 0.6943 (17) Å, θ = 92.19 (14)° and φ = 245.21 (14)° in molecule A [Q = 0.5265 (16) Å, θ = 112.63 (17)° and φ = 263.90 (19)° in molecule B] and the lactam ring (C9–C13/N1/O1) has a standard boat conformation (Cremer & Pople 1975). The two methoxy groups are slightly twisted from the attached benzene ring with the torsion angles C21–O2–C2–C3 = -21.3 (2)° and C22–O3–C4–C3 = -20.5 (2)° in molecule A [the corresponding values are -6.3 (2) and -16.2 (2)° in molecule B]. The benzamide moiety is not planar with the dihedral angle between the mean plane through C14–C15/N2/O4 and C15–C20 benzene ring being 8.97 (9)° in molecule A [8.10 (11)° in molecule B]. The orientation of the benzamide moiety can be described by the torsion angle C14–N2–C12–C13 = -92.77 (17)° in molecule A [-82.56 (18)° in molecule B] which shows the (-)-syn-clinal conformation with respect to the lactam ring. There are two stereogenic centers at atoms C12 and C9 (Fig. 1) or postions 3 and 11b of the tricyclic core of schulzeine. Fig. 1 show that H atoms at C12 and C9 are in cis-relationship. An intramolecular C10A—H10B···O3A weak interaction (Table 1; Fig. 1) generates a S(6) ring motif (Bernstein et al., 1995).
In the crystal packing (Fig. 2), molecules are linked into V-shaped dimers by N—H···O hydrogen bonds and C—H···O weak interactions (Table 1) which generate two S(7) ring motifs (Bernstein et al., 1995). These dimers are stacked into V-shaped columns along the a axis. Adjacent columns are further linked by C—H···O weak interactions in an antiparallel manner. C—H···π interactions were also observed (Table 1); Cg1 and Cg2 are the centroid of C1A–C6A and C15A–C20A benzene rings, respectively.
