3-(1-Adamantyl)-6-methyl-3-(3-methylbenzyl)isochroman-1-one

E. Babjaková, M. Necas and R. Vícha

Abstract top

In the title compound, C28H32O2, the oxanone ring adopts distorted half-boat conformation with the following Cremer and Pople puckering parameters: Q = 0.619 (2) Å, [theta] = 0.75 (19) and [varphi] = 172 (13)°. The dihedral angle betwen two benzene rings is 21.32 (7)°. The adamantane unit consists of three fused cyclohexane rings in classical chair conformations, with absolute values of C-C-C-C torsion angles in the range 57.5 (2)-60.9 (2)°. Weak interactions of the type C-H...O link molecules of each enantiomer into chains parallel to the b axis and lying about inversion centers. The crystal packing is also stabilized by intermolecular [pi]-[pi] stacking interactions [centroid-centroid distance of 3.8566 (11) Å].

Comment top

The title molecule is related to the isochromanone derivatives that are generally known as regulators of plant growth (Bianchi et al., 2004). In the dependence on their chemical structure and concentration they can act either as inhibitors or stimulators in these processes. Some substituted isochromanones isolated from myxobacteria strains were introduced as antifungal agents (Buntin et al., 2008).

The structure of the title compound (Fig. 1) consists of two essentially planar benzene rings with the maximum deviations from the best planes of 0.0046 (18) Å for atom C18 (benzene ring C13-C18) and 0.0115 (2) Å for atom C22 (benzyl group). The carbonyl plane (C18/C19/O1/O2) is also planar with the maximum deviation being 0.0073 (2) Å for atom C19. The dihedral angles between two benzene rings and between carbonyl plane and adjacent benzene ring are 21.32 (7) and 12.56 (6)°, respectively. The oxanone ring adopts distorted half-boat conformation with the torsion angles C12–C13–C18–C19, O1–C19–C18–C13 and C11–C12–C13–C18 being -2.3 (3), -10.8 (3) and 32.4 (2)°, respectively. The puckering parameters (Cremer & Pople, 1975) for the oxanone ring are Q = 0.619 (2) Å, θ = 0.75 (19)° and φ = 172 (13)°. The torsion angles describing alignment of adamantane cage and benzyl group C12–C11–C1–C2 and C12–C11–C21–C22 are 50.8 (2) and -69.7 (2)°, respectively. The adamantane cage consists of three fused cyclohexane rings in classical chair conformation, with absolute values of C–C–C–C torsion angles within the range 57.5 (2)-60.9 (2)°. The molecules of each enantiomer are linked via C23–H23A···O2 and C12–H12B···O2 weak interactions into chains parallel to the b-axis and lying about inversion centers (Table 1 and Fig. 2). The packing of the crystal is stabilized by intermolecular π-π stacking of isochromanone rings with the centroid-to-centroid (Cg: C13–C18) distance being 3.8566 (11) Å.

Experimental top

The title compound was prepared by the reaction of 3-methylbenzylmagnesium chloride with adamantane-1-carbonyl chloride in diethyl ether (Vícha et al., 2006). A solution of 3-methylbenzylmagnesium chloride (5 ml, 0.030 mol) in diethyl ether was added to a well stirred solution of adamantane-1-carbonyl chloride (0.8858 g, 0.004 mol) in 5 ml of dry diethyl ether at 273 K. The mixture was stirred for 72 h at room temperature and the reaction mixture was quenched with 15 ml of HCl (1 M). After additional 15 min of vigorous stirring, the aqueous layer was separated and washed three times with 15 ml of diethyl ether. Combined organic layers were washed with K2CO3 (1.16 M), dried over Na2SO4 and evaporated in vacuum. Crude product was purified on column (silica gel; petroleum ether/ethyl acetate, v/v, 16/1). The title compound was obtained as a colorless crystalline powder (350 mg, 41%), melting point 447–448 K). Crystals suitable for X-ray analysis were acquired by spontaneous evaporation from deuterochloroform at 298 K.

Refinement top

Hydrogen atoms were positioned geometrically and refined as riding using standard SHELXTL (Sheldrick, 2008) facilities, with their Uiso set to either 1.2Ueq or 1.5Ueq (methyl) of their parent atoms.

Special details top

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.
