In the title compound, C(12)H(18)NO(+)·Cl(-), the cations and anions are inter-connected by weak C-H⋯Cl hydrogen bonds. The morpholine ring system adopts a chair conformation.
Introduction The fungicidal properties of morpholines with large ring N-substituents was first reported in 1965 [ l ] and since then several (Fig. 1) have been marketed for the control of plant pathogenic fungi. Dodemorph, tridemorph, aldimorph and fenpropimorph are used to control powdery mildews and have both protective and eradicant properties. They are systemic in action, being absorbed thr...
The title compound, C(4)H(10)NO(+)·C(5)H(8)NOS(2) (-), is built up of a morpholinium cation and a dithio-carbamate anion. In the crystal, two structurally independent formula units are linked via N-H⋯S hydrogen bonds, forming an inversion dimer, with graph-set motif R(4) (4)(12).
Organocatalytic direct C3 alkenylation of indoles has been developed. Simple and readily available morpholine trifluoroacetic acid salt is employed as an efficient catalyst in this oxidative dehydrogenative reaction. Simplicity and practicality constitute the most attractive advantages of this reaction.
In the title mol-ecule, C(11)H(13)ClN(2)O(2), the morpholine ring has a chair conformation. In the crystal, mol-ecules are linked into chains along [100] by N-H⋯O hydrogen bonds.
four new complexes of the type [lco ((do)(doh) pn) cl] pf , where (do) (doh) pn = n , n '- propanediylbis (2, 3-butanedione2-imine3-oxirne)a nd l =morpholine (mrpln) (i), benzylamine (bzlan) (ii), piperidine (pprdn)(iii) and pyrrolidine (prldn) (iv) have been synthesized and characterized by elemental analyses and spectroscopic methods. approximate values of the angular-overlap parameter, ...
the velocity sedimentation of DNA prepared 4 hr after administration of from 1to 100mg/kg body weight nitroso morpholine were observed in both alkaline and neutral su crose gradients. The single-strand damage to DNA was not completely repaired 14 days after treatment while the double-strand breaks were more rapidly repaired. Injec tion of similar doses of either of the other two cyclic com poun...
A series of morpholine substituted amino acids (phenylalanine, leucine, lysine and glutamic acid) was synthesized. A fragment-based screening approach was then used to evaluate a series of small heterocycles, including morpholine, oxazoline, dihydro-1,3-oxazine, tetrahydro-1,3-oxazepine, thiazoline, tetrahydro-1,3-pyrimidine, tetrahydro-1,3-diazepine and hexahydro-1H-benzimidazole, as potential...
The title compound, C19H29NO4S, was synthesised from 9α-hy-droxy-parthenolide (9α-hy-droxy-4,8-dimethyl-12-methyl-ene-3,14-dioxatri-cyclo-[9.3.0.0(2,4)]tetra-dec-7-en-13-one), which was isolated from the chloro-form extract of the aerial parts of the plant Anvillea radiata. The mol-ecule is built up from two fused five- and ten-membered rings, with an additional ep-oxy ring system and a thio-mo...
