Ethyl 3-(4-methyl-benzene-sulfonamido)thieno[2,3-b]pyridine-2-carboxyl-ate.

ABSTRACT: The thieno[2,3-b]pyridine ring system of the title compound, C(17)H(16)N(2)O(4)S(2), is essentially planar, the amino and carbonyl groups being nearly coplanar with the heterocyclic ring system. There are two N-H?O hydrogen-bonding inter-actions involving the same N-H donor set and two different acceptors, one in an intra-molecular bond helping to fix the mol-ecular geometry and the other defining a dimeric structure around the symmetry centre at (0, , ).

Project description:In the title compound, C(17)H(20)N(2)O(2)S, the tetra-hydro-pyridine ring adopts an envelope conformation with the N atom at the flap position; the phenyl ring makes a dihedral angle of 81.06?(10)° with the thio-phene ring. The amino group links with the carbonyl O atom via intra-molecular N-H?O hydrogen bonding, forming a six-membered ring. In the crystal, inter-molecular N-H?O hydrogen bonds link the mol-ecules into infinite chains running along the b axis.

Project description:The title compound, C18H20N2O3S, exists as the phenol-imine form in the crystal and there are bifurcated intra-molecular O-H⋯(N/O) hydrogen bonds present. The conformation about the C=N bond is anti (1E); the C=N imine bond length is 1.287 (4) Å and the C=N-C angle is 122.5 (3)°. In the tetrahydrothienopyridine moiety, the six-membered ring has a flattened-boat conformation. In the crystal, mol-ecules are stacked nearly parallel to (110) and a weak C-H⋯π inter-action is observed. The carbonyl O atom is disordered over two positions and was refined with a fixed occupancy ratio of 0.7:0.3.

Ethyl 4-hydroxy-methyl-2-methyl-pyridine-5-carboxyl-ate.

Project description:The title compound, C(10)H(13)NO(3), was obtained as a by-product of the aldolization reaction of furo[3,4-c]pyridin-3(1H)-one with thio-phene-2-carboxaldehyde. The substituents on the pyridine ring are nearly coplanar, with an 8.1 (2)° rotation of the hydroxmethyl group from this plane. The mol-ecules assemble in the crystal structure as chains via O-H⋯N hydrogen bonding between the pyridine N atom and a neighbouring hydroxy-methyl OH group.

Ethyl 5-methyl-imidazo[1,2-a]pyridine-2-carboxyl-ate.

Project description:The title compound, C(11)H(12)N(2)O(2), was synthesized from the reaction of 6-methyl-pyridin-2-amine and ethyl 3-bromo-2-oxopropionate. In the mol-ecular structure, the six- and five-membered rings are individually almost planar with r.m.s. deviations of 0.003 and 0.002?Å, respectively. The two rings are almost coplanar, the dihedral angle between their planes being 1.4?(3)°. Inter-molecular C-H?O and C-H?N hydrogen bonds are present in the crystal structure.

Ethyl 5-methyl-4-oxo-3-phenyl-2-propyl-amino-3,4-dihydro-thieno[2,3-d]pyrimidine-6-carboxyl-ate.

Project description:The title compound, C(19)H(21)N(3)O(3)S, was synthesized via the aza-Wittig reaction of functionalized imino-phospho-rane with phenyl isocyanate under mild conditions. In the mol-ecule, the fused thienopyrimidine ring system is essentially planar, with a maximum deviation of 0.072 (2) Å, and makes a dihedral angle of 60.11 (9)° with the phenyl ring. An intra-molecular C-H⋯O hydrogen bond is present. The crystal packing is stabilized by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds.

Crystal structure of ethyl 3-amino-6-methyl-2-[(4-methyl-phen-yl)carbamo-yl]-4-[(E)-2-phenyl-ethen-yl]thieno[2,3-b]pyridine-5-carboxyl-ate monohydrate.

Project description:In the title mol-ecule, C27H25N3O3S·H2O, the dihedral angle between the planes of the thienyl ring and the pendant p-tolyl group is 39.25 (6)°, while that between the pyridine ring and the pendant phenyl ring is 44.37 (6)°. In addition, there is a slight twist in the bicyclic core, with a dihedral angle of 2.39 (4)° between the thienyl and pyridine rings. The conformation of the carbamoyl moiety is partially determined by an intra-molecular N-H⋯O hydrogen bond. In the crystal, complementary N-H⋯O hydrogen bonds form dimers which are then associated into chains parallel to the c axis through O-H⋯N hydrogen bonds involving the water mol-ecule of crystallization. Electron density associated with an additional solvent mol-ecule of partial occupancy and disordered about a twofold axis was removed with the SQUEEZE procedure in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18]. The given chemical formula and other crystal data do not take into account the unknown solvent molecule(s).
