چکیده
The title compound, C16H22Cl2O, was synthesized from β-himachalene (3,5,5,9-tetra-methyl-2,4a,5,6,7,8-hexa-hydro-1H-benzo-cyclo-heptene), which was isolated from the essential oil of the Atlas cedar (Cedrus Atlantica). The mol-ecule is built up from fused six- and seven-membered rings and an additional three-membered ring arising from the reaction of himachalene with di-chloro-carbene. The six-membered ring has an envelope conformation, with the C atom belonging to the three-membered ring forming the flap, whereas the seven-membered ring displays a screw-boat conformation; the dihedral angle between the rings (all atoms) is 59.65 (14)°.

The title compound, C48H75B3Cl6O3, was synthesized in two steps from β-himachalene (3,5,5,9-tetra-methyl-2,4a,5,6,7,8-hexa-hydro-1H-benzo-cyclo-hept-ene), which was isolated from the essential oil of the Atlas cedar (Cedrus Atlantica). The mol-ecule consists of an almost planar cyclo-triboroxane ring [maximum deviation = 0.036 (2) Å] linked to three identical fused ring systems with different c...

The asymmetric unit of the title compound, C16H24Cl2O2, contains two independent mol-ecules (A and B) which are built from three fused rings, viz. a seven-membered heptane ring, a six-membered cyclo-hexyl ring bearing a ketone and an alcohol group, and a cyclo-propane ring bearing two Cl atoms. In the crystal, the two mol-ecules are linked via two O-H⋯O hydrogen bonds, forming an A-B dimer with...
