A series of 3(2H)-furanones, based on side-chain modifications of a parent 3(2H)-furanone, was synthesized in good yield. The parent compound was prepared by hydrogenolysis, and subsequent acid hydrolysis, of isoxazole derivatives. The isoxazole was prepared by a [3+2] 1,3-dipolar cycloaddition reaction between 3-butyn-2-ol and nitrile oxide.

A novel and efficient one-pot cascade synthesis of 2H-1,4-benzoxazin-3-(4H)-ones has been developed through copper-catalyzed coupling of o-halophenols and 2-halo-amides. Various 2H-1,4-benzoxazin-3-(4H)-ones with diversity at three substituents on their scaffold have been synthesized conveniently in good to excellent yields.

In the title compound, C(15)H(10)O(2), a 3-phenyl derivative of the coumarin (also known as 2H-chromen-2-one or 2H-1-benzopyran-2-one) scaffold, the C(p)-C(p)-C(c)-C(c) torsion angle between the coumarin (c) ring system and the phenyl (p) ring is -47.6 (2)°.

BACKGROUND We evaluated the diagnostic rate of diabetes using fasting plasma glucose (FPG), 2-hour plasma glucose (2h PG) after 75 g oral glucose tolerance test (OGTT), and glycosylated hemoglobin (HbA1c) levels, and we elucidated the pathophysiologic characteristics and risk factors that give rise to diabetes in patients with prediabetes. METHODS The data of 236 patients who had the OGTT at ...

The role of endotoxin (lipopolysaccharide, LPS) and nitric oxide in hepatic oxygen metabolism was investigated in 36 pigs receiving 1) LPS (1.7 μg ⋅ kg-1 ⋅ h-1) for 7 h and N G-nitro-l-arginine methyl ester (l-NAME; 25 mg/kg) after 3 h, 2) LPS, 3) NaCl andl-NAME, and 4) NaCl. Infusion of LPS reduced hepatic oxygen delivery (Do 2H) from 60 ± 4 to 30 ± 5 ml/min ( P < 0.05) and increased the oxyge...

hBN-Encapsulated MoTe2 In article number 2205224, Gwan-Hyoung Lee and co-workers investigate phase transition in a laser-irradiated with various stacked geometries. Depending on the passivation temperature of sample, 2H-MoTe2 transforms into phases, such as Td, 1T′, Mo3Te4, Te. hBN-encapsulated MoTe2, 2H-1T′ heterophase can be patterned by local laser-irradiation, leading to low contact resisti...

In the present work, some MoS2 and WS2 nanosheets were prepared characterized. Depending on preparation procedures, trigonal prismatic (2H) or octahedral (1T) coordination of metal atoms obtained, exhibiting metallic semiconducting character. Both found large nonlinear optical (NLO) response, strongly dependent their So, character 2H-MoS2 2H-WS2 exhibit positive absorption strong self-focusing,...

Abstract Metallic conductive 1T phase molybdenum sulfide (MoS 2 ) has been identified as promising anode for sodium ion (Na + batteries, but its metastable feature makes it difficult to obtain and restacking during the charge/discharge processing result in part capacity reversibility. Herein, a synergetic effect of atomic‐interface engineering is employed constructing 2H‐MoS layers assembled on...
