The title compound, C13H13NO, crystallizes with four independent molecules in the The 12-membered penta[b]indole rings are essentially planar, with maximum deviations ranging from 0.034 (4) to 0.036 (4) Å in the four unique molecules. In the crystal, weak C—H⋯O interactions are observed, which link the molecules into chains along [010].

2-Chloroaniline (255 mg, 2.0 mmol, 1 equiv.), 2,2-dimethylcyclopentane-1, 3-dione (757 mg, 6.0 mmol, 3 equiv.), acetic acid (180 mg, 3.0 mmol, 3 equiv.), magnesium sulfate (120 mg, 1.0 mmol, 0.5 equiv.), and dimethylacetamide (6 mL) were added to a 25 mL round bottom flask. After bubbling argon through the mixture for 10 minutes, potassium phosphate tribasic (552 mg, 2.6 mmol, 1.3 equiv.) and Pd(t-Bu3P)2 (101 mg, 0.2 mmol, 0.1 equiv.) were added and the flask sealed with a septum. After bubbling argon through the reaction mixture for an additional 5 minutes, the flask was heated for 16 hours at 125°C. After the reaction was complete (monitored by TLC), the mixture was cooled to room temperature and filtered to remove insoluble material (Fig. 3). The filtered solids were washed with dimethylacetamide (3 x 2 mL). Water (40 mL) was added to the filtrate and the aqueous mixture was extracted with ethyl acetate (3 x 50 mL). The combined organic layers were dried over sodium sulfate, filtered, and concentrated in vacuo. The residue was purified by flash
(20% ethyl acetate in pentane) to yield the desired product (I) as a pale yellow solid (350 mg, 88%). Single crystals suitable for diffraction were grown from dichloromethane layered with pentane (liquid/liquid diffusion) at ambient temperature [m.p. 434–436 K (dec); literature value 433–435 K (dec) (Ouyang et al., (1994)].All of the H atoms were placed in their calculated positions and refined using a riding model with Atom—H lengths of 0.95Å (CH), 0.99Å (CH2), 0.98Å (CH3) or 0.88Å (NH). Isotropic displacement parameters for these atoms were set to 1.2 (CH, CH2 NH) or 1.5 (CH3) times Ueq of the parent atom. All methyl substituents were refined as rotating groups. The maximum and minimum residual electron density peaks of 0.69 and -0.33 eÅ-3 were located 1.38 Å, and 1.31 Å from the H12D, and C11D atoms, respectively.
Bruceolline D is a cyclopent[b]indole alkaloid which was first isolated from the root wood of Brucea mollis var. tonkinensis (Ouyang et al., 1994). Our total synthesis of bruceolline D was achieved by methylation of 2-methylcyclopentane-1,3-dione (Agosta et al., 1970) followed by a palladium-catalyzed
with 2-chloroaniline in 88% yield (Nazare et al., 2004). The reaction of phenylhydrazine with 2-methylcyclopentane-1,3-dione (Fischer indole synthesis) under thermal and acidic conditions has been investigated (Dashkevich, 1978). Other structurally similar bruceollines have been isolated more recently (Chen et al., 2011). Bruceolline E has been synthesized by a sequential Nazarov cyclization/selenium dioxide oxidation (Jordan et al., 2011) and the determined (Jordan et al., 2012). In view of the importance of cyclopent[b]indole we report here the of the title compound, C13H13NO, (I).The title compound, (I), crystallizes with four molecules in the
(Fig. 1). In the planar 12-member cyclopenta[b]indol-2(1H,3H,4H) rings, the maximum deviations from planarity are at C4A, 0.034 (4) Å, C3B, 0.034 (4) Å, C4C, -0.036 (4) Å and C4D, -0.035 (4) Å) atoms, respectively. Bond lengths are in normal ranges (Allen et al., 1987). In the crystal weak intermolecular C—H···O interactions are observed (Table 1) which link the molecules into chains along [010] and contribute to crystal packing stability (Fig. 2).For the first isolation of bruceolline D, see: Ouyang et al. (1994). For a Fischer indole synthesis approach to bruceolline D, see: Dashkevich (1978). For the methylation of 2-methylcyclopentane-1,3-dione, see: Agosta et al. (1970).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |

Bruceolline D is a cyclopent[b]indole alkaloid which was first isolated from the root wood of Brucea mollis var. tonkinensis (Ouyang et al., 1994). Our total synthesis of bruceolline D was achieved by methylation of 2-methylcyclopentane-1,3-dione (Agosta et al., 1970) followed by a palladium-catalyzed cyclization with 2-chloroaniline in 88% yield (Nazare et al., 2004). The reaction of phenylhydrazine with 2-methylcyclopentane-1,3-dione (Fischer indole synthesis) under thermal and acidic conditions has been investigated (Dashkevich, 1978). Other structurally similar bruceollines have been isolated more recently (Chen et al., 2011). Bruceolline E has been synthesized by a sequential Nazarov cyclization/selenium dioxide oxidation (Jordan et al., 2011) and the crystal structure determined (Jordan et al., 2012). In view of the importance of cyclopent[b]indole alkaloids, we report here the crystal structure of the title compound, C13H13NO, (I).
The title compound, (I), crystallizes with four molecules in the asymmetric unit (Fig. 1). In the planar 12-member cyclopenta[b]indol-2(1H,3H,4H) rings, the maximum deviations from planarity are at C4A, 0.034 (4) Å, C3B, 0.034 (4) Å, C4C, -0.036 (4) Å and C4D, -0.035 (4) Å) atoms, respectively. Bond lengths are in normal ranges (Allen et al., 1987). In the crystal weak intermolecular C—H···O interactions are observed (Table 1) which link the molecules into chains along [010] and contribute to crystal packing stability (Fig. 2).
