Ethoxy-carbonyl-methyl ursolate.

ABSTRACT: The title compound, C(34)H(54)O(5), was synthesized by the reaction of ursolic acid with ethyl chloro-acetate in the presence of DMA. All six-membered rings of the penta-cyclic triterpene skeleton adopt chair conformations. In the crystal structure, mol-ecules are linked by inter-molecular O-H?O hydrogen-bond inter-actions, forming zigzag chains along the c axis.

Bis[diamino-(ethoxy-carbonyl-amino)-methyl-ium] sulfate.

Project description:In the mol-ecule of the title compound, 2C(4)H(10)N(3)O(2) (+)·SO(4) (-), the cations are planar (r.m.s. deviations = 0.0144 and 0.0236 Å) and oriented at a dihedral angle of 62.30 (4)°. Intra-molecular N-H⋯O hydrogen bonds result in the formation of two planar six-membered rings. The cations are linked to the sulfate ion through inter-molecular C-H⋯O and N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

Project description:In the crystal structure of the title compound, C(7)H(11)N(2)O(2)S(+)·Cl(-)·H(2)O, the cations, anions and water mol-ecules are linked by inter-molecular N-H⋯O, N-H⋯Cl, O-H⋯O and O-H⋯Cl hydrogen bonds, forming layers stacked along [20].

Bis[2-(ethoxy-carbonyl-amino)ethan-aminium] hexa-bromidostannate.

Project description:In the title salt, (C(5)H(13)N(2)O(2))(2)[SnBr(6)], the Sn atom (site symmetry ) exists in a slightly distorted octa-hedral geometry. The cation is non-planar as the terminal CH(2)NH(3) (+) residue lies below the plane defined by the remaining non-H atoms. In the crystal, cations associate via N-H?O hydrogen bonds involving the ammonium and carbonyl residues, forming a 14-membered {?HNC(2)NCO}(2) synthon. The cations and anions are arranged in alternating layers arranged along the a-axis direction, the major association between them being N-H?Br contacts.

Ethyl 6-ethoxy-carbonyl-methyl-4-(2-hydroxy-phen-yl)-2-oxo-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate.

Project description:The title compound, C(17)H(20)N(2)O(6), belongs to the monastrol-type of anti-cancer agents and was selected for crystal structure determination in order to confirm its mol-ecular structure and explore some aspects of its structure-activity relationships. The central tetra-hydro-pyrimidine ring has a flat-envelope conformation. The 4-hydroxy-phenyl group occupies a pseudo-axial position and is inclined at an angle of 87.7 (2)° to the mean plane of the heterocyclic ring. Of the two ethyl ester groups, one (in the 5-position) is in a coplanar and the other (in the 6-position) is in a perpendicular orientation with respect to the heterocyclic plane. There is a three-dimensional hydrogen-bonding network in which all hydrogen-bond donors and acceptors are involved.

2-(1-Methyl-ethoxy)-5-nitro-phenyl N-methyl-carbamate.

Project description:In the title compound, C(11)H(14)N(2)O(5), the nitro group is approximately coplanar with the benzene ring, making a dihedral angle of 4.26 (17)°. The dihedral angle between the methyl-carbamate group and the benzene ring is 72.47 (6)°. There is a strong inter-molecular N-H⋯O hydrogen bond between the N and O atoms from adjacent methyl-carbamate groups, forming a one-dimensional network along the a axis.

(Z)-Methyl 3-(4-ethoxy-anilino)but-2-enoate.

Project description:The title compound, C(13)H(17)NO(3), was synthesized from methyl 3-oxobutanoate and 4-ethoxy-benzenamine using a catalytic amount of InBr(3) under solvent-free conditions. The 3-amino-but-2-enoic acid methyl ester group is planar and forms a dihedral angle of 83.4 (1)° with the benzene ring. The eth-oxy group is slightly twisted away from the benzene ring [dihedral angle = 13.8 (1)°]. An intra-molecular N-H⋯O hydrogen bond generating an S(6) ring is observed. Mol-ecules are linked into a chain along the b axis by inter-molecular C-H⋯O hydrogen bonding.

Methyl 3-[3-(ethoxy-carbon-yl)thio-ureido]-1H-pyrazole-5-carboxyl-ate.

Project description:The title compound, C(9)H(12)N(4)O(4)S, was proven to be the product of the reaction of methyl 5-amino-1H-pyrazole-3-carboxyl-ate with ethyl isothio-cyanato-carbonate. All non-H atoms of the mol-ecule are planar, the mean deviation from the least squares plane being 0.048?Å. The intra-molecular N-H?O bond involving the NH-group, which links the thio-urea and pyrazole fragments, closes a six-membered pseudo-heterocyclic ring, and two more hydrogen bonds (N-H?O with the participation of the pyrazole NH group and N-H?S involving the second thio-urea NH group) link the mol-ecules into infinite chains running along [10].
