18-Methoxycoronaridine was prepared according to the literature procedure (Bandarage et al., 1995) and treated in dichloromethane solution with excess of anhydrous HCl. The solvent was removed under reduced pressure, and the the residue was washed with benzene that gave the pure 18-methoxycoronaridine hydrochloride (sub: 195–197 C). X-ray quality crystals were grown from a methanol/THF solvent mixutre.
All non-hydrogen atoms were refined anisotropically. Hydrogens on carbon atoms were placed in calculated positions and refined using a riding model at C—H = 0.95, 0.98 or 1.00 Å and Uiso(H) = 1.2, 1.5 or 1.2 τimes Ueq(C) of the aryl, methyl and methine C-atoms, respectively. Methyl hydrogen atoms were set in staggered orientation and not optimized rotationally.
18-Methoxycoronaridine hydrochloride is a compound under investigation for anti-addictive and anti-leishmaniasis activity (Bandarage, et al., 1995) that has prompted a further study on additional, related systems (Kuehne, et al., 2003). Its structure is presented herein to aid these studies. The hydrochloride salt is readily obtained from pure 18-methoxycoronaridine by reaction with anhydrous hydrochloric acid. Though this salt readily crystalizes from a variety of solvents, it was found that ethanol/THF was the optimal system for affording X-ray quality samples. Desipte the conditions, no evidence for decarbomethoxylation was observed.

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. Suitable crystals were mounted in a nylon loop with Paratone-N cryoprotectant oil and data collected on a Bruker APEX 2 CCD platform diffractometer. The structure was solved using direct methods and standard difference map techniques, and was refined by full-matrix least-squares procedures on F2 with SHELXTL Version 6.14 (Sheldrick, 2008). 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. |

18-Methoxycoronaridine hydrochloride is a compound under investigation for anti-addictive and anti-leishmaniasis activity (Bandarage, et al., 1995) that has prompted a further study on additional, related systems (Kuehne, et al., 2003). Its structure is presented herein to aid these studies. The hydrochloride salt is readily obtained from pure 18-methoxycoronaridine by reaction with anhydrous hydrochloric acid. Though this salt readily crystalizes from a variety of solvents, it was found that ethanol/THF was the optimal system for affording X-ray quality samples. Desipte the conditions, no evidence for decarbomethoxylation was observed.
