8-Methyl-5-methylene-2-oxotricyclo[5.3.1.13,9]dodecan-endo-8-ol

Abstract top

The title compound, C14H20O2, crystallizes with homochiral chains of molecules hydrogen bonded together along the b axis. Adjacent chains in the ab plane contain molecules of the same chirality, leading to a chiral segregation of the molecules into layers.

Comment top

The preparation of this compound is part of a project involving alicyclic diols (Yue et al. 2002, 2006, 2007). The title compound (Fig. 1) crystallizes in space group P21/c with homochiral chains of molecules along b which are held together by O—H···O═C hydrogen bonding. Adjacent chains along a are of the same chirality, leading to chirally pure layers within the crystal which are shaded light and dark in Fig. 2. It is unusual to observe chirally pure layers within a centrosymmetric lattice. In this case the layer is generated by a combination of the 21 screw axis along b and translation along the short a axis, neither of which generates a change in chirality.

Experimental top

5-Methylidenetricyclo[5.3.1.13,9]dodecane-2,8-dione (Yue et al., 1997, 2000) was reacted with ca 1 equivalent of methyllithium in tetrahydrofuran solution. After standard work up of the reaction, the crude solid product was recrystallized to afford the title compound of m.p. 105–107°C. 13C NMR (75.5 MHz, CDCl3) δ: 28.1 (CH2), 30.9 (CH2), 31.9 (CH3), 34.7 (CH2), 38.6 (CH2), 38.8 (CH), 40.6 (CH), 42.7 (CH), 43.3 (CH), 45.3 (CH2), 74.8 (C), 119.3 (CH2), 148.2 (C), 219.9 (C). 1H NMR (300 MHz, CDCl3) δ: 1.44 (s, 3H), 1.83–1.98 (m, 4H), 2.01–2.21 (m, 4H), 2.29–2.47 (m, 4H), 2.66–2.76 (m, 2H), 2.99 (dd, J = 14.3, 7.1 Hz, 1H), 4.94 (d, J = 15.1 Hz, 2H). X-ray quality crystals were obtained from diethyl ether solution.

Refinement top

Hydrogen atoms attached to C were included at calculated positions (C—H = 1.0 Å). The hydroxy hydrogen atom was located on a difference map, and was then fixed at a position along the O···O vector with O—H = 1.0 Å. All hydrogen atoms were refined with isotropic thermal parameters equivalent to those of the atom to which they were bonded.
