A series of 1-methyl-2-methyleneacenaphthenes has been synthesized, bearing an additional variable substituent (R) at the 1-position. These compounds have been hydrogenated in ethanol over a 5% Pd/C catalyst under standardized conditions in order to assess the haptophilicity of R, its ability to enforce addition of hydrogen from its own face of the molecule(More)
The two delta-keto carboxylic acids of the title, both C(10)H(14)O(3), are epimeric at the site of carboxyl attachment. The endo (3alpha) epimer, (I), has its keto-acid ring in a boat conformation, with the tilt of the carboxyl group creating conformational chirality. The molecules form hydrogen bonds by centrosymmetric pairing of carboxyl groups across the(More)
The title compound, (1R,2R,3S,5S,8S)-3-hydr-oxy-8-methyl-8-azoniabicyclo-[3.2.1]octane-2-carboxylic acid chloride, C(9)H(16)NO(3) (+)·Cl(-), is both a metabolite and a precursor of the tropane alkaloid l-cocaine. The carboxyl group is not involved in dimerization, but instead donates a hydrogen bond to the chloride counter-ion, which participates in two(More)
The title compound, [Fe(C(6)H(5)O(2))(C(7)H(7)O)], adopts a conformation involving partial staggering of its rings and aggregates in the solid as acid-to-ketone hydrogen-bonding dimers [O.O = 2.720(4)A and O-H...O = 164 degree] having centrosymmetrically related components. Close intermolecular C-H...O contacts were found to both carboxyl O atoms.
The asymmetric unit of the title compound, C9H14O3, consists of two molecules having conformations that differ by a rotation of 111.7 (5) degrees about the equatorial substituent bond, so that the side chains of the two species extend away from the ring in different directions. Each conformer forms centrosymmetric hydrogen-bonded acid-to-acid dimers with(More)
In the the title compound, 1,7-dimethyl-8-oxo-4balpha,7alpha-gibba-1,3,4a(10a)-triene-10beta-carboxylic acid monohydrate, C18H20O3*H2O, the water of hydration accepts a hydrogen bond from the carboxyl and donates hydrogen bonds to the carboxyl carbonyl and the ketone in two different screw-related neighbors, which are mutually translational, yielding a(More)
The title ketocarboxylic acid, C5H6O3, is the smallest carboxycyclanone to have its crystal structure determined. It adopts a chiral conformation, by rotation of its carboxyl O atoms away from the plane of skeletal symmetry that passes through the carboxyl carbon and both atoms of the ketone carbonyl. The four-membered ring is non-planar, with a shallow(More)
In the title compound, C(15)H(24)O(3), derived from a naturally occurring sesquiterpenoid, the asymmetric unit consists of two molecules differing by 167.4 (8) degrees in the rotational conformation of the carboxyl group. Each molecule aggregates separately with its own type as carboxyl-to-ketone hydrogen-bonding catemers [O...O = 2.715 (6) and 2.772 (6) A,(More)
