Aromatic π-π stacking inter-actions stabilize the crystal structure of the title compound, C(10)H(12)N(2)O(3), the perpendic-ular distance between parallel planes being 3.7721 (8) Å. The morpholine ring adopts a chair comformation.

In the ionic title compound, K(+)·C(5)H(8)NOS(2) (-)·H(2)O, the morpholine ring of the morpholine-4-carbodithio-ate anion has a chair conformation. The potassium cation is coordinated by four S and four O atoms in a bipyramidal reversed geometry. In the crystal, the three components are linked, generating infinite two-dimensional networks that lie parallel to the bc plane. These layers are link...

In the title compound, C20H19NO4S2, the morpholine ring adopts the expected chair conformation. The central phenyl ring makes dihedral angles of 67.97 (4) and 7.74 (3)°, respectively, with the benzoate phenyl ring and the morpholine mean plane. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming zigzag chains along the b-axis direction. C-H⋯π inter-actions link centrosymmetri...

Morpholine-substituted 1,8-naphthalimide fluorophores exhibit solvent and pH-dependent emission characteristics based on aggregation, form robust chemically reversible metallogels.

The title compound, C(24)H(39)NO(2) (systematic name: 4-{[1,4a-dimethyl-7-(propan-2-yl)-1,2,3,4,4a,5,6,7,8,9,10,10a-dodeca-hydro-phenanthren-1-yl]carbon-yl}morpholine), has been synthesized from Δ(8)-dihydro-abietic acid. Two cyclo-hexene rings adopt half-chair conformations, whereas the cyclo-hexane and morpholine rings are each in the chair conformation. Two methyl groups are in an axial posi...

The title compound, C(28)H(30)N(4)O(2), synthesized from 4-[1-(4-ethoxy-phen-yl)-5-methyl-1H-1,2,3-triazol-4-yl]diphenyl-meth-an-ol and morpholine, consists of a subsituted triazolyl group and a morpholinyl group that crowd the aliphatic C atom of a diphenyl-methyl unit [C(triaz)-C-N(morph) = 110.1 (1)° and C(phen-yl)-C-C(phen-yl) = 103.9 (1)°]. The morpholine ring adopts a chair conformation.

A method was developed to monitor the in vivo formation of N-nitrosomorpholine. N-Nitroso(2-hydroxyethyl)glycine, a major urinary metabolite of N-nitrosomorpholine, was quantified as its methyl ester-trimethylsilyl ether derivative, using gas chromatography with nitrosamine-specific detection. When the method was applied to rats, the in vivo formation of, or exposure to, as little as 0.6 microg...

The crystal structures of piperazine, piperidine and morpholine have been determined at 150 K. All three structures are characterized by the formation of NH...N hydrogen-bonded chains. In piperazine these are linked to form sheets, but the chains are shifted so that the molecules interleave. In morpholine there are in addition weak CH...O interactions. Topological analyses show that these three...

Morpholine-2,5-dione derivatives having substituents with benzyl-protected carboxylic acid, benzyloxycarbonyl-protected amine and p-methoxy-protected thiol groups, respectively, were prepared in 2958% yield by cyclization of the corresponding N-[(2RS)-bromopropionyl]L-amino acids. Polyesteramides with protected pendant functional groups were obtained by ringopening copolymerization of either &-...

Using a method for nitrosamine analysis that gives high recovery values and that is free from artifactual synthesis of nitrosamines, we have shown that human feces do not contain volatile nitrosamines (detection limit, 0.1 to 0.5 /ng/kg). We also showed that nitrosation reactions are not catalyzed by fecal organisms. Following a 2-day anaerobic incubation of feces with either a secondary aminé...
