Crystal Structure Prediction of Inorganic Materials: A Benchmark and Modern Evaluation
Predicting a crystal’s structure from composition alone is a long‐standing challenge in materials discovery. The CSP180 benchmark of 180 inorganic crystals evaluates thirteen crystal structure prediction algorithms requiring no density functional theory (DFT) against DFT‐based baselines across twelve metrics.

Chronic morpholine exposure of rats
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

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.

Three-Step Synthesis of N-(7-chloro-4-morpholinoquinolin-2-yl)benzamide from 4,7-Dichloroquinoline
The quinoline derivative, N-(7-chloro-4-morpholinoquinolin-2-yl)benzamide, was synthesized in a conventional three-step procedure from 4,7-dichloroquinoline using a N-oxidation reaction/C2-amide formation reaction/C4 SNAr reaction sequence. The structure

Synthesis of enantiopure 3-substituted morpholines
Enantiopure 3-substituted morpholines were assembled through ring-opening of a N-2-benzothiazolesulfonyl (Bts) activated aziridine with organocuprates followed by a ring annulation reaction with a vinylsulfonium salt under microwave conditions ...

Cyclodehydrohalogenation-beta-Lactams-Morpholin-3-ones-H'-NMR Spectroscopy N-Aryl-N-chloroacetyl-2-chlorophenacylamines (2) give morpholinones 3, or beta-lactams 4, depending upon the N-aryl-substituent. N-Phenyl-N- (2,3-dibromo-3-phenylpropionyl) -4-nitrophenacylamine did not undergo base-catalysed cyclization but gave, instead, the α,β-

Expedient and Rapid Synthesis of 1,2,3-Triazolo[5,1-c]morpholines through Palladium−Copper Catalysis
A one-pot approach using palladium−copper as catalyst has been developed for the synthesis of morpholines fused with 1,2,3-triazole. Good regioselectivity, mild reaction conditions, high yields and short reaction time are the hallmarks of this ...
