(6R,10R)-Dimethyl 1,4-dioxaspiro-[4.5]decane-6,10-dicarboxyl-ate.

ABSTRACT: The title compound, C(12)H(18)O(6), is in the usual chair conformation with the two ester functions in a 1,3-trans orientation. With a value of 1.439?(2)?Å, the pseudo-axial C-O bond of the 1,3-dioxolane ring is slightly longer than the corresponding equatorial C-O bond of 1.424?(3)?Å. The O-C-O angle of the dioxolane ring is 106.25?(17)°.

The title compound, C(12)H(18)O(6), is in the usual chair conformation with the two ester functions in a 1,3-trans orientation. With a value of 1.439 (2) Å, the pseudo-axial C-O bond of the 1,3-dioxolane ring is slightly longer than the corresponding equatorial C-O bond of 1.424 (3) Å. The O-C-O angle of the dioxolane ring is 106.25 (17)°. ...[more]

rac-Diethyl 9-hy-droxy-9-methyl-7-phenyl-1,4-diaza-spiro-[4.5]decane-6,8-dicarboxyl-ate.

Project description:The title mol-ecule, C(21)H(30)N(2)O(5), is chiral with four stereogenic centres. The crystal is a racemate and consists of enanti-omeric pairs with the relative configuration rac-(6S*,7R*,8R*,9S*). The ethyl fragment of the eth-oxy-carbonyl group at position 6 is disordered in a 0.46?(3):0.54?(3) ratio. The crystal structure features inter-molecular N-H?O. Intra-molecular O-H?N and N-H?O hydrogen bonds also occur.

Dimethyl 2,6-dimethyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate.

Project description:In the crystal of the title compound, C(11)H(15)NO(4), the mol-ecules are linked into sheets by N-H?O and C-H?O hydrogen bonds. Within the mol-ecule, the 1,4-dihydro-pyridine ring exhibits a distinctive planar conformation [r.m.s. deviation from the mean plane of 0.009?(3)Å], and the other non-H atoms are almost coplanar [r.m.s. deviation = 0.021?(3)?Å] with the 1,4-dihydro-pyridine ring. The conformation of the latter is governed mainly by two intra-molecular C-H?O non-classical inter-actions.

Diethyl 2,6-dimethyl-4-phenyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate.

Project description:The title mol-ecule, C(19)H(23)NO(4), was synthesized by the reaction of benzaldehyde, ethyl acetoacetate and NH(4)HCO(3). The dihydro-pyridine ring adopts a flattened boat conformation and the plane of the base of the boat forms a dihedral angle of 88.78?(9)° with the phenyl ring. The packing is stabilized by strong inter-molecular N-H?O and weak inter-molecular C-H?O hydrogen bonds.
