organic compounds
In the title compound, C11H14O2, the tetrahydropyran ring adopts a 1C4 conformation, with the phenyl and the hydroxy substituents located in equatorial positions. Hydrogen bonding occurs in the solid state between hydroxy groups to link two molecules of (R,R)-trans-4-phenylperhydropyran-3-ol and two molecules of the (S,S)-enantiomer to provide tetramers.
organic compounds
The title compound, C12H12O2S2, is a chiral O,S-dialkyl dithiocarbonate. The O-ethyl substituent and the dithiocarbonate functionality form a plane, which is twisted by 60.7 (2)° from the S-(3-oxoindan-1-yl) group.
organic compounds
The title compound, C14H18BrFO, is a hexasubstituted tetrahydropyran with two halogen atoms attached in β and four C substituents in α positions with respect to the ether O atom. The CC distance [3.183 (7) Å] between the two 1,3-diaxially oriented α-methyl groups falls below the sum of the van der Waals radii. The magnitude of the bond angle at oxygen [122.6 (3)°] and a comparatively small displacement of this atom [0.490 (5) Å] from the mean plane of four C atoms of the tetrahydropyran ring indicate a marked flattening of the heterocyclic ring in its 1C4 conformation.
