A chemical genetics approach has been applied in the screening of yeast deletants strains with a pool of morpholine-derived compounds in order to identify candidate small molecules able to produce phenotypic effects on yeast cells. The analysis of the effects of structurally diverse molecules towards cell growth rate in both exponential and stationary phases provides a tool to select candidate ...
In the crystal structure of the title compound, C(18)H(19)N(2)O(+)·BF(4) (-), bifurcated N-H⋯(F,F) hydrogen bonds link the protonated 4'-morpholine-methyl-biphenyl-2-carbonitrile cations and slightly distorted tetra-fluoro-borate anions. π-π inter-actions [centroid-centroid distance = 3.805 (3) Å] help to consolidate the packing. The dihedral angle between the benzene rings in the cation is 57....
In the title compound, C12H13N3O, the morpholine ring adopts a chair conformation and its mean plane is inclined to that of the benzene ring by 16.78 (12)°. The N-N=C-C bridge, which has an E conformation, has a torsion angle of 173.80 (19)°. In the crystal, mol-ecules stack along the a axis but there are no significant inter-molecular inter-actions present.
Michael addition reactions of morpholine and benzylamine to methyl 2,3-dideoxy-4,6-0-(phenylmethylene)-3-Cphenylsulfonyl-a-D-erythro-hex-2-enopyranoside 9 furnish glucoderivatives 10 and 11. Desulfonation at C-3 followed by synthetic manipulation produces intermediates for generating various new modified monosaccharides carry ing N-alkyl and N,N-dialkyl amino groups at the C-2 position of hexop...
In the title compound, C(16)H(13)N(3)OS, the thio-morpholine ring exists in a screw boat conformation. The angle between the benzimidazole ring system and the benzene ring fused to the thia-zine ring is 67.22 (6)°. In the crystal, mol-ecules form infinite chains along the a axis via inter-molecular N-H⋯N inter-actions. C-H⋯π inter-actions also contribute to the stability of the crystal structure.
In the title mononuclear dioxidovanadium(V) complex, [V(C(13)H(16)BrN(2)O(2))O(2)], the V(V) atom is five-coordinated by one phenolate O, one imine N and one morpholine N atom of the Schiff base ligand, and by two oxide O atoms, forming a distorted square-pyramidal geometry. In the crystal, weak C-H⋯O inter-actions and a short Br⋯Br contact [3.4597 (12) Å] are observed.
In the title compound, C13H18N2O3, the benzene ring makes a dihedral angle of 17.19 (11)° with the least-squares plane formed by the four C atoms of the morpholine ring, which adopts a chair conformation. In the crystal, C-H⋯N hydrogen bonds link the mol-ecules into supramolecular chains running along a 21 screw axis parallel to the b-axis direction. Weak C-H⋯π inter-actions are also observed.
9-formyljulolidine was oxidized via a microwave-assisted Willgerodt-Kindler reaction to the N-piperidine or N-morpholine julolidine-9-thioamide. 9-formyl-1,1,7,7-tetramethyljulolidine gave the corresponding N-piperidine tetramethyljulolidine-9-thioamide. The thioamides were converted to the corresponding carboxamides with trifluoroacetic anhydride. The amide group directed ortho-metalation in t...
The title compound, C(9)H(10)N(2)S, was synthesized according to Gewald procedures by the reaction of cyclo-hexa-none with malonitrile and sulfur in the presence morpholine. The cyclo-hexane ring adopts a half-chair conformation and the thio-phene ring is essentially planar (r.m.s. deviation = 0.05 Å). The crystal packing is stabilized by two inter-molecular N-H⋯N hydrogen bonds, which link the...
The reaction of copper(I) iodide with N-acetyl-thio-morpholine (L, C6H11NOS) in aceto-nitrile results in a coordination polymer with composition [CuI(L)2] n . The CuI atom is coordinated by two S atoms and two I atoms, adopting a distorted tetra-hedral environment. The μ2-bridging mode of the I atoms gives rise to chains extending parallel to [010]. C-H⋯O hydrogen-bonding inter-actions between ...
