(Morpholin-4-yl)[2-(morpholin-4-yl)-3,5-dinitrophenyl]methanone
Acta Crystallographica Section E, 2012 In the title compound, C15H18N4O7, the morpholine rings adopt chair conformations. The benzene ring forms dihedral angles of 55.94 (7) and 63.19 (7)° with the planes through the C atoms of the two morpholine rings.

Chronic morpholine exposure of rats
Fundamental and Applied Toxicology, 1989 The chronic toxicity and carcinogenic potential of morpholine were evaluated in 60 Sprague-Dawley rats/sex/group receiving morpholine at mean inhalation exposure concentrations of 0, 10, 50 and 150 ppm for 6 hr/day, 5 days/week, for 104 weeks. Survival, body weight gains, organ weights, hematology, and clinical chemistries were normal in exposed groups

Angewandte Chemie International Edition, EarlyView.A pyridine‐containing ligation auxiliary eliminates a major bottleneck of peptide ligation chemistry. The extended range of applicable pH values (2.0–7.5) in the ligation reaction helps to avoid epimerization. Native chemical ligation (NCL) proceeds at virtually any junction, including reactions at β‐branched amino acids, as well as O‐glycosylated or O‐

2-Deoxystreptamine Conjugates by Truncation–Derivatization of Neomycin
Pharmaceuticals, 2010 A small library of truncated neomycin-conjugates is prepared by consecutive removal of 2,6-diaminoglucose rings, oxidation-reductive amination of ribose, oxidation-conjugation of aminopyridine/aminoquinoline and finally dimerization.

Zeitschrift für Naturforschung B, 1970 ω- (N-aryl-chloracetamido) -acetophenones have been cyclized with triethylamine in warm benzene solution to the corresponding 1,4-oxazines. The reaction appears to be general for any N-aryl substituent, as long as an overall electron-withdrawing substituent is present para- or meta, in the aromatic nucleus of the acetophenone moiety.

Anatomical Sciences Education, Volume 18, Issue 3, Page 241-253, March 2025.Abstract This study describes the process of developing a high‐impact, low‐cost, and low‐maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection ...

Bulletin of the Korean Chemical Society, EarlyView.Abstract DNA‐encoded libraries (DELs) enable large‐scale screening for hit identification, but accessing sp3‐rich, three‐dimensional chemotypes beyond flat, aromatic scaffolds remains challenging. Multicomponent reactions (MCRs) assemble such complexity from simple building blocks in a single step, and reaction‐engineering strategies have extended on ...

, 2017 The survival of coherent wavepacket motion during internal conversions is observed in relatively large molecules,N-methyl morpholine andN-ethyl morpholine, where standard models imply fast decoherence in a statistical limit.
