The title compound, C18H26ClNO2, is one of a group of
decahydroisoquinoline derivatives that are known to exhibit a diverse range of bioactivities. The piperidine and cyclo-hexanone rings exist in chair conformations and form a cis -fused decalin-type bicyclic framework. In the crystal structure, in®nite zigzag chains oriented along thebaxis are formed by
OÐH O intermolecular hydrogen bonds.
Comment
The title compound, (I), is one of a group of decahydroiso-quinoline derivatives that are known to exibit a diverse range of bioactivities, including antibacterial and, most importantly, antimalarial activities (Nakagawa, 2000). Considerable effort has been made in these areas to design new analgetic drugs (Menardet al., 1974; Ripka, 1978, 1979, 1984). There are also studies devoted to the discovery of novel classes of NMDA
receptor antagonists (Hansen et al., 1998) and selective
iGluR5 receptor antagonists (Martinelliet al., 1998, 2001).
Compound (I) was produced in a one-pot cascade Michael addition intramolecular aldol reaction sequence and isolated in the form of the salt with hydrochloric acid. The bicyclic part of (I) takes the form of a cis-fused decalin-type framework (Fig. 1). Both six-membered rings have chair conformations. All methyl groups attached to the piperidine ring and the phenyl group attached to the cyclohexanone ring occupy equatorial positions. The chloride anion is connected to the nearest H atom at the piperidine N atomviaa hydrogen bond (Table 1). There is an intermolecular hydrogen bond between the hydroxy group and carbonyl atom O1 at (ÿx,1
2+y,12ÿz),
forming in®nite zigzag chains along thebaxis (Fig. 2).
Experimental
Sodium hydride (65% suspension in mineral oil, 0.42 g) was added in small portions, with constant stirring, to a solution of 1,2,5-tri-methylpiperidin-4-one (1.5 g, 0.01 mol) in anhydrous dimethylform-amide (30 ml). One hour later, benzalacetone (1.16 g, 0.008 mol) was added dropwise, with stirring, at room temperature and a solution of enolate was obtained. The reaction mixture was allowed to stand for 3 d. Addition of water, extraction with benzene, washing with water
and recrystallization from cyclohexane gave 0.8 g (27.8% yield) of the base compound of (I) (m.p. 439±441 K). Crystals of the chloride, (I), were obtained by the addition of diethyl ether/HCl to the solution of the base in diethyl ether (m.p. 518±520 K). Analysis calculated: C 63.17, H 7.89, N 4.09, Cl 10.38%; found: C 63.72, H 7.98, N 4.33, Cl 10.79%. IR (cmÿ1): 1705 (C O), 3300±3500 (OH). 1H NMR

Special details
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.
